Hi! I've got a 10 gal tank with 8 male guppies in it. I would like to get something to eat algae, but I don't think I can fit any more fish. I like corys and otos, but I don't think my tank can support them. Could I get a mystery snail? I don't want it just for the algae, i think it would be fun to have in my tank. Is it worth it?
