Hi I have 4 little rbp In a 50 gallon tank and just bought a 90 gallon 48Lx18Wx24H for them U can see them in my vid in the pic and vid forum. Well I was wondering what your guys opinions are about me getting 1 or 2 more when I move them to the 90? They might be in the 90 for life but not sure I want to upgrade to bigger tank but out of funds right now. Well Anyways I would say they are 3/4 an inch and I would buy the same size. I want to have the decent shoal for my 90 gallon. I am putting 2 Ac 500 on it and a powerhead and a interior filter and later either a home built wet/dry or a ehiem canister filter. I just want what would be good for both me and my p's. Thx for any replies.
