hmm I don't see anywhere that says "hi my tank is full of algae and I am getting a fish to fix it" The question was "what are the best algae eaters for a community tank?"
depend on the size of tank, and these guys are correct in my opinion. Siamese Algae Eater (not chinese), Oto's, Shrimp and small plecos unless you have a huge tank and you can get common plecos.
