I'm looking for something to help control the algae problem in my 180l tank. I will be adding 10 or so amano shrimp once my LFS gets them back in stock, but I want something else that is an efficient algae eater. I like otocinclus, but I wonder if something so small would be able to cope in a large tank? Other options are either a BN or CAE? Anyone got any other suggestions or recommendations?
