Thanks everyone! I think if they're still alive tonight after work, it will be the longest they've gone with free swimmers. The parents are hyper defensive, which is neat to see. If I get close to the glass they flip out. They, of course, need a water change. But I'm not doing anything for awhile. This morning I added a little clump of java moss since there's not much cover at the bottom of the tank. They moved the fry about halfway across the tank and then the parents were taking turns going over and attacking the moss. I can't say it wasn't entertaining. The dad really thought a little piece that he broke off was going to kill them all.
