I just got back from a fish swap and my girlfriend picked out a calico long fin BN pleco. It's still tiny and a baby. She also has been eyeing a fluval edge and hinting to me since her birthday is in a week. She refuses to get a larger thank and only wants the fluval edge. She wants the pleco to go in the edge. I looked on aqua advisor and they said 15 gallons minimum for a BN pleco. But I wanted to make sure on here. Would the fluval edge be to small for a bn pleco. I do 50% weekly water changes anyway. I think I already know the answer but I guess it's worth a try. She is really depressed because she loves the fish and wants it in a tank of her own.
