a friend of mine had a pair of Texas rats housed together years ago and during feeding they both grabbed either end of a mouse and the one swallowed the other half way down before she noticed. luckily she was able to pull them apart and they both survived. another time a different friend of mine had a pair of adult gabbons housed together, he separated them to feed them but when he returned the male to the cage the female struck and drove both of her 1 1/2" fangs into the males head. needless to say he died almost instantly. so for me even for the purposes of a large display exhibit, I think that housing more than one specimen per enclosure is just asking for trouble
1. Keeping two snakes together = not asking for trouble.
2. Feeding two snakes together = asking for trouble.
I thought gaboons were immune to their own venom..............
