Grin Ghost Posted June 12, 2022 Share Posted June 12, 2022 Is it ok to have an all male group of the dwarf neon rainbowfish? I'm thinking of adding these amazing fish to my tank but have never kept them before. Is there agression between males if there are no females in the tank? Do the males show the same amount of color if there are no females? Thanks in advance! Link to comment Share on other sites More sharing options...
