So my son's tank has gotten too violent. He's tired of losing fish. We're down to a single Zonatus and 5 clown loaches in that tank now, and when the Zonatus comes out of that tank, I need to stock it with something. He doesn't want a single big fish, he likes the "community" setup. All I can think of is a fancy Pleco. What would go good with a Pleco in a 75? Rainbow fish? He doesn't want Sajica's either. I'm outta ideas.
