I know a 90 gallon is kinda small to you guys but i got a good deal on it. I did the small schooling fish thing and now i want something bigger and better. I will be thinning it out but the fish that will stay for right now are the 2 bristle nose plecos and my 2 eclipse/sun catfish. They are only 1.5 in right now. What other catfish can i add to this tank?
