Not a great idea. Ive got a friend, whose 50 and an "old school" snake keeper. He does it and i try to convince him otherwise but he aint budgin. He's just been lucky so far. 60 gal sounds a bit large for a bp.
from what i have heard, a while ago, it was accepted practice to keep multiple BPs together. in the last 20-30 years how people keep these animals have changed A TON.
