Another update, they are one month old tomorrow. There are only 3-5 remaining. The male went through a psychotic episode and ate most of the fry and beat the female up very badly.
The largest of the fry is about the 3/8" if I had to guess. They have only been eating scraps of the brine shrimp and bloodworms I feed the parents, I imagine if I had separated them and fed them first bites or similar fry food they would be much larger by now.
Enjoy.
