i have a black sailfin molly and a balloon molly that seem to like eachother very much. But the odd thing is that sometimes i catch the black one flaring his sailfin and doing weird "dances" and "waggles" next to the balloon one. The balloon seems to completly ignore this but the black one will do this for 5 or so minutes then its back to normal. Im quite confident they are both males so im sure its not a mating ritual. Any idea what this behavior might be?
