Well, things didn't go as well as hoped. None of the eggs hatched, and now almost all are gone. Not sure if they were eaten by the parents or just burried in the gravel by the parents, but I don't see 'em anywhere. This was their first time as parents, so, as someone suggested, maybe they just need some practice. They're alone in a 110g, so I think I'll leave them in there and see if they can get it right next time. Thanks everyone.
