I just found a whole bunch of eggs my clown percs laid last saturday. How long does it take for them to hatch. There are about 50 to 60 small red dots attached to an under piece of LR and I believe the male is guarding them with his life. He won't let anything near them. Once they hatch, what am I supposed to do. The two percs are the only fish in that tank along with snails and crabs that are acting as my cleanup crew.
