Well, Dan, as you know, I have an Iowa snow plains and an albino checkered. I house them together, they are both males...close in age...Possum is around a year old and Hermes is 10 mos old. They were both captive bred. In terms of temperament, they are both the sweetest snakes in the world...but they do tend to be a bit skiddish...Hermes, the T.marcianus is a bit more skiddish than Possum, the T.radix. T.radixes have a reputation as being very social snakes. Possum is the one with the neuro disorder...he enjoys playing peek-a-boo games with me...and likes to coil around my fingers. Interestingly for an albino...he seems to like light...I put a little bit of light on his enclosure every day and he comes out more if there is some light on. Because he is in the enclosure with Hermes, who does not like light, I only use a red bulb for heat...with a UTH for additional heat as needed. Hermes only comes out at night. Both of them are very nocturnal by nature. They both also love climbing and hanging out in the top of their fake trees....they also enjoy basking sometimes under the red light. Possum loves tilapia...Hermes loves pinkies. Oh, and interestingly...Hermes will only eat if I put his food under his hide and then stick him in his hide with it. After he is done, I always find him....fat and happy lying on the dish under the hide! Possum rolls in his food dish and gets food all over him...attacking his food as though it were alive! I love watching him eat. Possum loves to eat. They are both awesome snakes to have. They love being together and sleep curled up together. Great thread, Dan!
