I have a 29 gallon cichlid tank. I want to have a low lighted planted tank. Well, I have a huge pleco. I've heard he will eat the plants and should look into getting something else. My b/f has SAE's in his tank and seem to do fine. But, I had brown algae thats why I got the pleco in the first place. So what bottom eaters will eat this brown algae without being lunch for my cichlids???
