Learn about Amazon Basin Emerald Tree Boas

The Emerald Tree Boa is a species of arboreal Boa discovered in 1758 by Carlos Linnaeus. Carlos originally named the emerald tree boa, Corallus Caninus.  Corallus, the genus name comes from the coral-like color of this species. Caninus comes from the snake’s head, snout and canine teeth which resemble a dog.

There are two types or species of the emerald tree boas, the Surinam, also known as the Guyana Shield Emerald Tree Boa and commonly named the Northern Emerald Tree Boa (Corallus Caninus), and the other is the Amazon Basin Emerald Tree Boa (Corallus Batesii recently distinguished from the Corallus Caninus). These two types of Emerald Tree Boas have distinct differences in their location or geography as well as morphology. The Northern Emerald Tree Boa is found in Northern South America whereas the Amazon Basin Emerald Tree Boa is found along the Amazon River basin in southern Suriname, southern Venezuela to Colombia, Peru, Brazil, and in the surrounding jungles of the Amazon River.

Northern Emerald Tree Boas

Northern Emerald Tree Boas are smaller in size, length and girth, averaging 4-6 feet long. Whereas the Amazon Basin Emerald Tree Boas are much thicker and average 7-9 feet in length. The Northern is shiny light green with white lateral markings that show down the back of the snake with a creamy white belly. The Amazon Basin is a darker green shade with white triangular or diamond shaped markings that protrude from the white dorsal stripe that goes down the back of the snake, with a yellow belly. Both species live to 20-30 years of age.

Amazon Basin Tree Boa Terrarium

Our terrariums range in the size and type, depending on the age and size of the emerald tree boa. The neonates stay in the Mini/Tall Terrariums measuring 12” x 12” x 18” (WxDxH). The juveniles are moved to Small/Tall Terrariums measuring 18” x 18” x 24” (WxDxH). As the juveniles mature and grow in size then are moved to the larger Medium/Tall Terrarium measuring 24” x 18” x 24” (WxDxH). The adult emerald tree boas live in the Large/Tall Terrariums measuring 36” x 24” x 30” (WxDxH). We keep the terrariums together based on size, stacked on three leveled racks. The Exo Terra Glass Terrarium are ideal for the younger neonates and juvenile amazon basins, specifically for arboreal boas who live off the ground.  These cages are naturally tall giving our amazon basins the ability to climb. The terrariums front opening doors allow for easy access for maintenance and feeding. The top of the terrariums is full screen for ventilation and UV penetration. For emerald tree boas, this can also create problems for humidity reasons. To solve that issue, we cut plywood to properly fit the top screen sections, leaving one section open for ventilation and the white light/red light fixture. The adult amazon basins are moved to the larger terrariums that we had made by Boa Masters. You can see in the photo to the left showcasing the adult basin enclosures.


Each terrarium is setup with a Day/Night Tropical Lighting Kit made by Zoo Med. The Lighting Kit has a white 25-watt Repti-Basking Spot Lamp, and a red 50-watt Nocturnal Infrared Heat Lamp. During the day, the white light is set to run most of the day from 7am to 6pm, although will turn off if the temperature exceeds 85 degrees fahrenheit. The snake room is well lit with plenty of natural sunlight. During the evening, from 6pm to 7am if the temperature drops below 73 degrees fahrenheit, the red heat lights will turn on and bring the temperature back up. The lighting systems are controlled to run these day/night cycles by the ReptiCare® Terrarium Controller made by Zoo Med.

We live in Southern California where the average temperature is 77.1 degrees, and we keep the snake room temperature at 81 degrees. So unlike other areas of the world, where snake owners have trouble with temperatures, we don’t have that problem. Without much temperature manipulation, we can maintain a daytime ambient of 83-85 degrees and a nighttime of 75-78 degrees. For temperature control, we use Vivarium Electronics VE-300X2 Thermostats. Each rack of same sized cages has one thermostat to maintain the temperature control over all terrariums.

Vivarium Electronics VE-300X2 Thermostat Temperature


Emerald tree boas require a specific temperature and humidity range to maintain good health. If the temperature if too high or low, that could cause digestion problems. If the humidity is too high, that could cause respiratory issues. To achieve the proper humidity of 70-80%, we mist the cages once per day at 4-5pm using a 3 gallon compression pump sprayer. The entire cage must be sprayed, including the flooring substrate and plants.


For humidity reasons and to create a better environment for the snakes, we use fake plants that stick to the side walls of each terrarium, and live pothos plants at the bottom of each terrarium.

These snakes are arboreal boas therefore stay off the ground for most of their lives. Each terrarium is setup with a very natural looking perch system, created by Ron Rundo. Ron customizes every perch by hand, specific to the size of the terrarium and needs of the owner. The perches are made of epoxy resin, painted with acrylic paint then coated with semi-gloss polyurethane for durability.

Feeding, Shedding and Record Keeping

We regulate the feeding for each snake based on several aspects such as: their size and age, when was their last bowel movement, are they’re going into shed.  We always feed our animals at night.

Going into shed
1. Amazon Basins go into shed every 3-6 months depending on their size and age.
2. About 3-4 weeks before the snake sheds, you will notice a difference in their behavior. Emerald Tree Boas are nocturnal animals so they sleep all day on their perch, then are active at night. When they’re going into shed, the remain inactive during the day and night.
3. You will notice the snake fades from its natural lime green color to a dull gray tint.
4. During this time, the animal does not eat so don’t try to feed him.
5. As soon as the snake sheds, they will usually also have a bowel movement, and will be ready to feed.

Bowel movements:
1. It is extremely important to keep good records of your animal’s food intake, shed cycle, and bowel movement.
2. You don’t ever want to feed your snake too many meals between bowel movements. A good rule of thumb is 3 meals maximum until your snake goes to the bathroom.
3. If your snake is having troubles passing a bowel movement and has had three meals, you can put your snake into the shower. Make sure the shower is on warm, a temperature you would enjoy. Build a perch system you can put into the shower (example use PVC pipes). In the wild emerald tree boas go to the bathroom when it rains. It’s a defense mechanism as the rain washes their bowel movement away, and thus not attracting predators. It’s been my experience, the snake will go to the bathroom within 5-10 minutes of being in the shower.

Size and age:
1. Neonates feed every 10-14 days
– Frozen/thawed pink/fuzzy rats
2. Juveniles feed every 12-20 days
-Frozen/thawed fuzzy/hopper rats
3. Adults feed every 14-28 days
-Frozen/thawed small rats

Record Keeping
1. This is extremely important! If you have read everything above, then you know it’s a lot to remember. You do not want to forget the last time you fed your snake or when was their last bowel movement.
2. Record every meal, every bowel movement, every shed, when you change their water, clean their cage, everything!
3. I keep a spreadsheet of every snake and track all the above.

Learn about Boa Constrictors

Boa Constrictor Anery het VPI male

The Boa Constrictor is without question one of the most popular snakes being kept by snake lovers today. Once considered to be a rare and exotic pet, boas are now being bred in large numbers, both by hobbyists and commercial breeders. The increased availability, combined with an ever-increasing palette of selectivity bred colors and pattern anomalies, has catapulted the “common boa” into stardom among reptile keepers. The boa constrictor is a large snake, although it is only modestly sized in comparison to other large snakes, such as the reticulated python and Burmese python, and can reach lengths from 3–13 ft depending on the locality and the availability of suitable prey. Clear sexual dimorphism is seen in the species, with females being larger in both length and girth than males.

The usual size of mature female boas is between 7 and 10 feet, and males between 6 and 8 feet. Boas are very long-lived reptiles. There are documented cases of captive boas living longer than 40 years; however, the average captive life span is 20 to 30 years. Please consider this carefully before bringing a boa home. Depending on the subspecies, Boas can be found through Central America to South America and many islands along the coasts of Mexico and Central and South America. Boas generally live on their own, and do not interact with any other snakes unless they want to mate. They are nocturnal, but they may bask during the day when night-time temperatures are too low. As semi-arboreal snakes, young boa constrictors may climb into trees and shrubs to forage; however, they become mostly terrestrial as they become older and heavier.

It is very important to allow your new boa to acclimate to its new surroundings before feeding. Never attempt to feed a new boa for at least five days after you bring it home. I assure you your new boa will be fine without food during this time. If you feed it too soon, while it may still be stressed from the move to your home, the snake may regurgitate. If this occurs, be sure your temperatures are correct, and do not attempt to feed the boa again for two weeks. The most common causes of regurgitation are improper temperature and stress from being handled, so be sure you provide proper cage temperatures and do not excessively handle boas after meals. Never feed a new boa a meal that is larger than the snake’s mid-body girth. It should never exhibit a bulge after eating. Especially in young boas, a meal that is too large may lead to regurgitation.

An established boa will handle a meal resulting in a small bulge just fine. Pet boa constrictors should be fed only quality mice or rats. They need no additional food or supplementation. Be sure you buy your rodents from a good source to prevent disease and mites. Boas 2 years old and younger should be fed one appropriately sized rodent every seven to 10 days. Excessive feeding may lead to regurgitation, improper growth, and even premature death. Once boas near adulthood, they will thrive while being fed every 10 to 14 days. Most boa constrictors available as pets will be eating frozen/thawed prey. If you purchase one that is eating live rodents, it will often take frozen/thawed prey that is presented from a pair of tongs. Pre-killed rodents are always best, whether they are frozen/thawed or freshly killed, because live rodents may harm your boa. If your snake does not kill its prey (boas will not eat if they are not hungry or are kept under improper conditions), the rodent may bite or even kill your boa. Even if the boa does constrict its prey, the rodent may bite before it is killed. Never leave your boa unattended with live rodents.

Water, Humidity and Shedding

A water bowl is a necessity. This allows your boa a place to drink and helps provide the proper humidity for your boa. The humidity in the cage should be 60 to 70 percent; use a hygrometer (humidity gauge) to track the percentage. Water must always be clean and should be changed as needed and the bowl cleaned. Some boa constrictors will defecate or urinate in the water, which must be cleaned immediately if this occurs. Be sure to scrub and rinse the bowl, using an antibacterial dish soap and hot water. Be sure to rinse thoroughly, and run the water bowl through your dishwasher monthly if possible. Disposable forms of water bowls, such as deli cups, are another option. Young boas will often soak before or during a shed cycle. This aids in shedding their skin, but usually occurs only when proper cage humidity is not being met. A boa that is constantly in the water bowl usually indicates the humidity is too low, the temperature is too high, or the boa has mites. After a shed, be sure to check the tip of your boa’s tail.

Young boas will sometimes retain a small piece of shed skin there. If caught soon after the shed, this old skin is usually easy to remove by gently pulling the skin off. Always be careful when attempting this. If it’s sticking, usually a dip in warm water will make removal easy. This skin retention does not necessarily mean you have husbandry issues. Sometimes the skin simply tears before the shed is removed completely. If you notice retained skin on other areas of your boa’s body, you may need to adjust the humidity levels. Shedding issues are usually a result of insufficient humidity. A soak or two during the shed cycle will greatly help if you are experiencing low-humidity issues. Place a quarter-inch of warm water in an appropriately sized plastic container, and place your boa inside with a secure lid in place. Then place the container in your boa’s cage, positioned so the inside of the container has a warm side and cool side. This will keep the water warm and the humidity high. Do not place it directly over the belly heat or under a basking bulb. A few holes in the lid or sides of the container will provide ventilation. Soak your boa in the container for up to an hour (two hours if you’re combating a particularly tough shed) and repeat as necessary. Be sure to check on your boa regularly, as they will often defecate while soaking. Change the water and clean the container if this occurs. At end of the shed cycle, remove the water and place a small towel in the container so your boa can rub on it to help shed its old skin.

Caging/Rack Systems

Many caging options are available for boas. Aquariums can be used, but reptile-specific plastic enclosures made from high-quality plastics that maintain proper humidity are much more suitable for boas than anything else. A rack system is something to consider should you advance into breeding boas, or if you plan to have many boas living with you. Custom enclosures are another option. Young boas have simple needs; a large, beautifully decorated cage is not the best choice for them. While a new boa is acclimating, simple housing is preferred, and the enclosure should be prepared prior to your new boa’s arrival home. An appropriate first cage for a baby boa would be no larger than 30 inches long by 12 inches wide, in which it will feel very secure. Naturally, as the young boa grows, a larger cage will be required. Boas are terrestrial and floor space is more important than height.

Boa Constrictor IMG Sharp male

Young boas may climb, but do so much less as they grow. Typical full-grown adult boas should be housed in cages no smaller than 4 feet long by 2 feet wide (with larger-than-average snakes in larger enclosures). A hide box/shelter should be provided, which will allow the boa to feel safe and secure. There are many commercially manufactured types available. Offer two hides, one on the warm side of the enclosure and one on the cool side. A stressed baby boa may stay on one side of the cage if only one hide is provided, which may discourage the snake from thermoregulating properly. You may also provide rocks, sticks or other structures, but be sure they are positioned securely and free of parasites.


Boas control their body temperature through thermoregulation, and the cage should have a warm side and a cool side. This is very important! Do not place the heat source in the center of the cage, place it at one end. Then if the boa gets too warm, it will move toward the cooler side, and if it is too cool, it will move to the warmer side. That’s thermoregulation! The temperatures in the cool end your boa cage should not drop below 75 degrees Fahrenheit. The warm side should be 85 degrees, with a hot spot of 90 degrees provided by an under-cage heating device that will provide “belly heat.” Boa constrictors greatly prefer this, so they can coil over the rising heat. Belly heat can be provided using various devices. Under-tank heaters are the most readily available. Heat cable and heat tape are other possibilities. Any heating device should be controlled with a proportional thermostat or rheostat.


Some heat sources, especially heat tape, can get too hot for some enclosures, and they must be regulated not just for the boa’s safety, but yours, too. If using these devices, especially if you’re using a glass enclosure such as an aquarium, be sure some ventilation is provided around the heat source. If heat builds up, it can crack the bottom of a glass tank, or cause other caging materials to melt or overheat. Overhead lighting is not usually needed. If an overhead bulb is used, it should be placed directly over the source of the belly heat. Be sure to check the temperature of your hot spot while the bulb is on. If the belly heat being provided from the under-enclosure device is not warm enough, overhead lighting will assist in maintaining a proper hot spot, but overhead lighting or an overhead heating device alone is not recommended for boas. A low-wattage fluorescent bulb can be used to provide a photoperiod (day/night cycle) and to better observe your boa. Full-spectrum bulbs with UVB may provide physical and physiological benefits to boas, but this has not been proven. UVB lighting is not needed for the proper care of boas, and the vast majority of boa keepers do not use it. Still, it won’t harm your boa, so feel free to provide it just in case there is some benefit.

Floor Substrate

Boas can be kept on several types of substrate. Newspaper, aspen, white or brown butcher/wrapping paper, and cage carpet are the most often used substrates. Fir and cypress barks are also acceptable but not often used by breeders. If using cypress bark or mulch, be sure it does not become too damp as it holds humidity very well. When using aspen or carpet, the cage can be spot cleaned often, with a full change occurring as needed. If using paper, the entire substrate should be changed each time cage cleaning occurs.

During the breeding season (November-April), the female boa emits a scent from her cloaca to attract males. While breeding, the male curls his tail around the female’s and the hemipenes are inserted. Copulation can last from a few minutes to several hours, and may occur several times over a few-week period. After this period, ovulation may not occur immediately, but the female can hold the sperm inside her for up to one year. When the female ovulates, a midbody swell can be noticed that appears similar to the snake having eaten a large meal. The female then sheds two to three weeks after ovulation, in what is known as a post-ovulation shed which lasts another 2–3 weeks, which is longer than a normal shed. The gestation period, which is counted from the post-ovulation shed, is around 100–120 days. The female then gives birth to a litter size that varies, but can be between 10 and 65 young, with an average of 25.

Handling Boas

Boa constrictors are usually very docile and tolerate handling very well. They often seem to enjoy being held and will seek out an area on your arm or shoulders and enjoy your body warmth. They may crawl around for a few minutes before hunkering down to grab some heat. If your boa seems to have a bad attitude, check its enclosure temperatures, humidity levels and overall husbandry. Most boas calm quickly after repeated sessions of being handled. The boa constrictor makes a great pet for reptile hobbyists of all levels, and it remains a cornerstone in the reptile community. Personally, I believe boa constrictors are as good as it gets in the snake world.

Learn about Ball Pythons

Ball Python female Orange Dream Yellow Belly Fire

The Ball Python is quite simply the most popular pet python in the world. Ball pythons are generally a bit shy, but they make for ideal captives, because they are of a small size, are generally friendly, are easy to care for, and come in a remarkable array of colors and patterns.

Ball pythons are native to central and western Africa and thrive in these warm, tropical areas. They are known as the royal python in many parts of the world and are revered in some areas of Africa.

Ball pythons make for a quality pet for the first-time keeper and experienced herpetoculturists alike. Each year, breeders create incredible, innovative, never-before-seen pattern and color variations that continually generate new fans of the ball python.

Ball python hatchlings are approximately 10 inches in length. Adult female ball pythons average 3 to 5 feet long, and adult male ball pythons average 2 to 3 feet in size. This is a species in which mature females are typically much larger than the males. A 5-foot ball python is considered big, although lengths of 6 feet or more have been reported. With proper care, ball pythons can live 30 years or more. The record age for a ball python is more than 40 years – so plan on a long life for your new pet snake.

Caging/Rack Systems

Ball python enclosures can be as simple or as elaborate as you want to care for. Remember that the more you put in the cage, the more you have to clean and disinfect on a regular basis. That said, there are different enclosures that work well for ball pythons, including, but not limited to, plastic tubs or melamine racks. At our facility, we use Freedom Breeder rack systems (see image). Glass aquariums and tanks are adequate for ball pythons, but the screen tops on such enclosures can make it very difficult to maintain proper humidity levels. Juvenile ball pythons seem to do well in small enclosures that make them feel secure. A small snake in a big cage can become overwhelmed and stressed. Adult ball pythons do not require exceptionally large or elaborate enclosures either. A 36-inch by 18-inch by 12-inch enclosure will more than comfortably house an adult ball python. The one cage accessory that is required for a happy ball python is a good hide box. Ball pythons are secretive snakes that appreciate and utilize hide spots. Provide one on each end of your python’s enclosure so that it doesn’t have to choose between temperature and security.

Freedom Breeder Rack System


Remember that enclosures must allow for a proper thermal gradient that the ball python can utilize, with a hotspot on one end of the enclosure and a cool spot on the other. Provide your ball python with a basking spot temperature of 88 to 96 degrees Fahrenheit and an ambient temperature of 78 to 80 degrees. The ambient temperature should not fall below 75 degrees. Ball pythons seem to prefer humidity levels of 50 to 60 percent. Maintaining proper humidity will allow your ball python to shed properly.


Floor Substrate

Newspapers and paper towels are the cheapest and easiest substrates for ball pythons with regards to cleaning and disinfecting. Aspen, cypress mulch and orchid bark are great substrates for controlling humidity, but remember that too much humidity can be as detrimental (if not more) as too little. Avoid sand, shavings and peat bedding.

Feed your ball python an appropriately sized rodent weekly. “Appropriately sized” means prey items that are no bigger in circumference than the ball python at its largest circumference. Ball pythons can eat rats from the time they are young – starting off with rat pups or “crawlers” at first and moving up in size as they grow. Do not handle your ball python for at least a day after feeding, as this can lead to regurgitation. Ball pythons can be fed frozen/thawed or pre-killed rodents. Never leave a live rodent unattended with any snake, as they can injure the snake.

Ball Python female Albino Black Pastel

Ball pythons are well-known for not eating at certain times throughout the year, particularly in the winter months. Be prepared for the possibility of your ball python going off feed, and keep an observant eye on the snake’s overall condition and body weight. This is typically nothing to worry about with healthy, well-established pythons, although it can be extremely frustrating to the snake keeper. If your ball python is healthy, continue your husbandry routine as usual, but keep the amount of handling to a minimum. Offer your ball python food every 10 to 14 days until it is interested in eating again, as the snake will eventually resume feeding normally.Feed adult ball pythons every 1 to 2 weeks and younger ball pythons weekly as they need this energy to grow. Do not be alarmed if a well-started ball python goes off feed during the cooler, drier times of the year, as this is common in captivity. Snakes generally do not eat while they are in the shed cycle.


Always have fresh, clean water available for your ball python. Check the water daily. The size of the water dish is up to you. If it is large enough for the ball python to crawl in to and soak, sooner or later your snake will make the most of the opportunity – ball pythons seem to enjoy a nice soak from time to time. Ensure that the water bowl is not too deep for juvenile animals – 1 inch or so will suffice. Snakes of many species will defecate in their water bowls from time to time, so be prepared to clean and disinfect the water bowl. The water bowl should be cleaned and disinfected on a weekly basis. Having a spare water bowl for such occasions can be handy, so that one may be used while the other is being cleaned.

Ball Python male Pastel Yellow Belly SK Axanthic


Ball pythons are generally shy and will spend much of their time hiding. Your ball python may initially see you as a threat and it must learn who you are. The goal is to establish trust between you and your snake.

Always support your ball python’s body and avoid fast movements. Once a ball python realizes that you will not hurt it they often seem to enjoy being handled. Some ball pythons may try to hide when handled and occasionally there are ones that may even bite due to excessive fear. These ball pythons may require a bit more time to settle in and establish trust. A ball python’s bite is a superficial wound. If a snake looks like it is going to strike, it is best to not handle it. Relax when holding your animal – sit down and give the animal a chance to settle.

Ball Python females Pied

Some snakes may not eat for several hours or longer after being handled, so avoid handling if you plan to feed. After a snake has eaten it may be a good idea to limit the handling because it may be uncomfortable for the animal. Avoid putting your snake’s cage in a heavy traffic area, excessive movement, and other pets should be avoided.
