I have a 55 gallon planted community aquarium. My stocking is 8 cardinal tetras, 8 cherry barbs, 8 serpae tetras, 1 blue ram, 1 pleco, 4 zebra danios, 2 corys, 2 blue gouramis,1 gold gourami, and 1 raphael catfish. Can i possibly add some rainbowfish. I particularly like boesemans rainbow fish. does anybody have any suggestions of other rainbowfish i could put in?
