So I just bought a all set up 20 gal long tank and everything is good but my nitrate (witch I'm working on with constant water changes suggested by my local fish store). I have 1 maroon clown, one royal gramma, one mystery wrasse, and one pigmy hall fish. I'm working on rehiring all but the maroon and getting a little male for her. I want to do all coral wig the two clowns. Any suggestions on resilient anemones and coral for a newby?
