Garden tree boa

Overview
The Corallus Hortulanus or amazone tree boa (ATB) is a small sized boa. Usually 150 to 200 cm in length. I bought my first couple in October 2004. Import animals from Surinam at Henk Wassenaar, one red male and a grey female.

Size
Average size 1.5 -2 meter

Housing
The Corallus Hortulanusare males are housed seperate in cages build from shuttering plywood 62 cm long, 75 cm wide and 60 cm high. I use newspaper as a substrate. The females are housed per 2 in cages build from shuttering plywood 125 cm long, 75 cm wide and 60 cm high. I use newspaper as a substrate with some branches and a flat spaces where the ATB’s can rest on.

Housing baby snakes
I use very small tubes with the opening at the front side.
The food offered from the front instead of above. Most predators attack baby snakes from above and they feel more secure when you feed from bellow or in front.
I have a flat space (see picture newborn setup), almost against the ceiling with some plastic leaves so the baby snakes feel save.

Temperatures
The temperature gradiënt varies between 24-26 degrees Celcius on the cool side with a basking site of
28-32 degrees Celcius.

Humidity
Humidity around 60% daytime and 90%. Nighttime.
I spray once a day, 1 hour before the lights go out.

Lighting
The light period being used is 12hrs on and 12hrs off. When using lights also as heatsource make sure you put the light to one side of the enclosure. So don’t put it right in the middle. By putting it to the right side or left side of the enclosure you will create a warm side and a cooler side of the enclosure. This way your boa can choose for himself/herself what they want. Also put the waterbowl on the cool side of the enclosure, don’t put it underneath the light, this may cause waterrot. We use 28 watt lights, this creates about 28 – 30 degrees celsius as a hotspot.

Feeding
Newborn boa’s will feed mostley a few days after the first shed. They need the first year a small enclosure with a lot of hiding places at the bottom and some higher hidding places. with a lot of leaves. Feeding from newborn untill the age of 2 years old it’s very important to feed every 7 days only proper sized preys. After 2-3 years they can be fed every 2 -3 weeks a small rat.

Feeding baby ATB’s
The first 3-5 times i feed in the evening with a red light head light.
I use pre-killed baby mouse and heat them in almost boiled water and try to feed the baby snakes. If they don’t take the baby mouse within 10 seconde I wil re-heat the baby mouse. I will repeat this till the baby ATB grab the baby mouse.

Halloween phase vs Garden Phase

Same or different?

This is an age old argument that I suspect will never end, but they are very different! Halloween phase falls into the category of garden phase simply because the base colours are “earth tones” just in the same way that both a yellow phase and a red phase both fall into the category of coloured phases. And the differences between the 2 are as easy to see as the differences between a yellow and a red when you know where to look!

** It is NOT orange markings as a neonate that distinguishes a Halloween phase, garden phase can have these highlights also. 

** Head patterning is the single biggest giveaway difference between Halloweens and gardens- Gardens typically display the head stripes with clean, bold patterning central to the top of the head. Versus Halloween phase who show a “confetti” style dashing to the top central aspect of their heads, often as neonates these markings are yellow or orange but will fade to white on an adult animal

** Garden phases can be all shades of earth tones as neonates, halloweens are typically black or very occasionally brown. As adults Halloween phases are almost always a combination of black, grey and white

Blond

Genetic: Dominant
The first Blonds i  saw are from Tanja Milja Keskinen. They breed an male from a Finnish breeder (probably with the Blond gene) with a female from Paris reptiles they got 2 blond amazon tree boa’s. They had 2 litters where one of the litters produced 2 blonds and the other litter didn’t produced a single blond.

More breedings need to be done to prove the genetics.
First 2 pictures are from yearling blond Amazon tree boa and the third from animal at the age of 2.

Calico melanistic
Genetic: dominant gene
The melanic calico has a lot influence melanic that will give the animal a lot of black pigmantation,
The black pimantation will develop within the first years.

The Candy cane variety with much less appearance of melanin in its color pattern, becoming practically or totally devoid of melanism.

Foekline calico
The first calico’s from the foekline bloodline are from a patternless yellow male(Born at dutch breeder) and patternless red female.(bred at an german breeder)
When breeding 2 foekline calico’s together some baby’s are so different than the normal calico’s. Maybe we have a super calico line. More breedings need to prove the genetics. (2019)
