Hey everybody. I recently got a 220 (6x2x2.5), resealed it, water tested, and drilled my holes for the plumbing to a 40 gallon sump. The tentative plan is for 2 adult oscars, potentially a small adult spotted gar, and a then a few uaru and severum. This seems to be a near full stocking list. Are there any catfish that I could house in this tank comfortably for life? Options are limited and my top choices are a hard no go (RTC and shovelnose). I can post pictures along the way if anybody is interested in the process.
