What should i or could i put in my new 150 gallon? I have an Oscar, Dempsey, firemouth and catfish right now but want something big and fun to have. The tanks dimensions are 48" by 24" by 30" and some fish im interested in are clown knifes, fire eels, Datnoids, Bichr and other oddballs.
Most bichirs would do fine in that tank, but ck's, dats, and fire eels would all outgrow it (well, except maybe the dat, I don't know much about them but I think they get pretty big).
The catfish is a synodontis flavitaeniatus. If you look on the overflow you can see its dorsal fin. I might be getting rid of him though because of my stock.
