About to start a 20 gallon community tank. It will have 1 dwarf gourami, 1 blue neon tux guppy, 1 black molly, 1 red wag platy, 6 Cardinal Tetras, and some shrimp and snails. Is there a bottom feeding fish that is about 3 inches or less that is ok with being the only one of its kind? Thanks!
I have a rubberlip in my 55 and he is only about 2.5-3"... I have a clown in my 20 long and he is about the same size but the rubber lip is much more personable...my clown stays behind the sponge filter or under the driftwood most of the time
