I have a 55 gallon with SA/CA cichlids in it. I want to get a bottom-dwelling fish that eats algae for it. Im looking for something that isnt expensive (not over 10 dollars) and could fit in the 55 for a while. I also have a 20 gallon with a convict and a goldfish in it. What could I possibly buy for that tank. If anyone doesnt know of any bottom-dwellers that eat algae suggest some non algae eating ones because I need some bottom-dwellers because my tanks are bare in that department thanks.
