My male and female dovii mated once again a week ago and had around 200-300 fry. Both parents were very protective of them and the mom was always by their side. When I turned on my tank lights this morning there are no fry in sight and there are some dead ones lying in the rocks. My male and female are on opposite sides of the tank and my male won't even come out from underneath his rock. This is unusual because he is always chasing me back and forth when I walk through the room. What's going on?!
