Thinking about getting a fish or snails or something that remove algae. One thing about snails is, the fish might eat them. Ive thought of clams but I dont think they get on the glass, only stay on the ground. As far as fish, theres pleco's and Algae eater, but plecos crap alot and get big, same with algae eaters and they get aggressive too. What would be a good candidate to get for algae in the tank and on the glass?
