it turns out 21 of the fry survived to this day. My LFS was willing to take 15 for $90 store credit, a great deal for them and for me. It's a win-win. I kept the parents and the six smallest to grow them out a little more.
This has been a fun journey, I didn't expect it when I put the parents in solitary confinement for roughing up other fish in my 75 gallon tank.
