I have a 90 gallon tank currently has only convicts and 2 plecos since they bread so fast i moved other fish out. I was wondering if a tank with divided territories would work with convicts and puffers I really like these 2 fish because of how active they are. My gf has 1 puffer and they are verry entertaining. She doesn't add salt or anything and its been fresh water for several years now. Any opinions?
