Hi all, I recently moved my zebra danios to a larger tank but kept the old smaller tank with some water in, in order to maintain a snail population as we were considering getting a pgymy puffer. The tank has had no filter and only a small amount of water in it as we weren't too worried about the snails (they breed so prolificly!) but my partner noticed today that there seems to be some fish fry in there. By removing the fish and the filter it seems we have inadvertently allowed eggs to hatch. Having not planned to breed the danios I don't know how to care for the fry so would appreciate any tips and suggestions, please.
