The Clown Loach has been recommended to me for controling snails in my tank once I dedide to add plants. My problem is that the Clown can grow more then I would like. My tank is a 46 gallon bowed design. I've choosen community fish (Neon Tetras, Gouramis and shrimp and such) which are all smaller size fish. I need a species that will eat the snails and if possible, also eat any unwanted algee. Is there such a species or could anyone recommend anthing? I will use two species if I need to. I'm mainly concerned about the Tetras and the shrimp (blue claw wisker type).
