I really wish I'd built the tank larger so I could accommodate some of the larger species, like an Oscar or a H. Psittacus, but I had to bargain with the live-in girlfriend to get this tank in the living room. literally had to sell her on every foot of the tank and compromised on the size I have, and I even made it a foot longer than she agreed to (hahah). but really would love more space. oh well
