I was contacted today by the individuals marketing the Black Tail Anerythristics in the classifieds. They requested background information on the bloodline.
Here is what they were told:
I purchased the parents of your animals in 2000 as yearlings. they were sold to me as 100% het for albino from someone that I trust. To date, I have produced two litters of babies from these adults. The albino trait has not proven out. Although it's possible that they are indeed het for albino: I have heard of hets that did not reproduce the het trait until the third or fourth breeding, but it is my belief that they are not.
Right from the start, I was impressed with the coloration of what is now my adult pair. They both have jet black tails and are anerythristic in appearance. You can see pictures of the adults, as well as pictures of the 2003 litter from which your boas originated at: http://reptiliandreams.com/btcolombian.html
The interesting thing with this bloodline is that they breed 100% true. Every baby looks this way. The first year that I produced babies (2002) all of the babies were sold very quickly. When I produced the 2003 litter, I took several of them with me to the Daytona Expo to get the opinion of other breeders. Everyone I showed them to felt that they were anerythristic. I sold a few of these at Daytona (including your pair to Jeremy Stone) as Black Tail Anerythristics because that was what everyone including myself felt they were. After Daytona, I was in no hurry to market them and had the opportunity to see them grow up a little.
It was after a couple of months that I noticed a very slight pink coloration on two of the remaining babies. It was very limited, in fact on one of the animals it only showed on a couple of individual scales. Now remember, I had not kept any from the first litter long enough to see this and my adult pair have never shown any hint of pink or red coloration. But since I was seeing this exhibit itself in two of the babies, I immediately dropped the name Black Tailed Anerythristic and marketed the remaining animals as Black Tail Colombians.
Now we all know that some anerythristic animals can display slight bits of coloration, especially as they grow, but I simply didn't want to risk misleading anyone.
At the very least, this is an unusual bloodline that breeds true. My future plans include breeding them into other anerythristic bloodlines to prove out compatibility.
It's also possible that this is simply a new variation. Time will tell.
If anyone else has any questions regading the bloodline, feel free to contact me at: mike@reptiliandreams.com
