A couple months ago, I moved my two year old albino-erythristic male in with my three year old albino male. Before I did this, the ery/albino was impossible for anyone but me to get out of his tank without being bitten (very food aggressive, and he thought everything was food) and was constantly hiding. The albino, which I'd had for about two years, was completely impossible to handle. Absolutely flipped out whenever anything touched him, and had to be completely restrained/would musk on everything the time or two I had to get a retained eyecap or tail tip off him.

After two months of living together, both of their behavioral issues have completely disappeared. Completely. I'm especially surprised by the albino, who will suddenly just let me pick him up and handle him. I expected them to maybe calm down a little bit, but definitely nothing this drastic.

Has anyone else ever seen behavior change that dramatically when you move two snakes into the same tank? It's been so drastic I've actually started checking on them more regularly to make sure they aren't sick (they don't appear to be and I can't think of any reason they would be).
