hey guys, i currently have a 14" rb pacu, 14" bullhead catfish or i think a channel cat? and a 9" purple rose queen. so my dad's been telling me how my tank looks disgustingly boring and dull and wants me to get some other fish. something that i could probably have in a group of lets say 3-5 and are monsters that have some color, or active and grow less than a foot i'd say. so is there anything out there you think i could keep? i'm also planning on keeping my 14" catfish. i previously wanted another fahaka puffer, but my dad's like if you can only keep one then no cuz he thought it was boring until feeding when i had one. so what are the options out there?
