Hello, I was wondering if I could add a BN or other small type of pleco into my tank. This is a 29 gal. 2 killifish 2 platies 7 cories 1 flying fox or SAE. It is supposed to be a SAE, but doesn't hardly eat algae 1 GBR I have a bad algae problem. I bought the SAE or at least it was supposed to be a SAE for that problem. It is far from fixed. Thanks!
