Gorgeous photo!!!
I didn't know the Dumerils did that. Our local pet store has one...
As for the Boelen, if I recall correctly, there is an interview on Herp Radio Network (Herp Nation Radio Network??) that mentions them. It was the episode on Repti-Links, and if memory serves, the interviewer breeds them. Might be worth looking up. There is also a Boelen forum that, at a glance at least, seems to be current. (I was very distracted by the Boelen for a few days a couple of months ago.)
