Have him about a week in a 10 gallon. Bought him a live plant today since the man at the store told me he needs that algae since my tank may not be produciong enough without it. (I only have fake plants and decor). Problem is my tank is about full, I may be able to stick another guy in there if he really truly needs one. Anyone know some legitmate information on oto socialization to help them live the longest? Thanks!
