Having the same problem with my Festaes, its getting frustrating. I had 2 Jags in with them and fed nite clawlers to them and 3 days later the Jags laid eggs. I removed the Jags and frie leaving the Festae by themselves but no luck yet. They act like they are getting ready to breed but no eggs. When I first bought them at the 4" mark my female had her tube showing and havent seen it since. I must have interupted the process when I bought them and removed the fish from thier sale tank. Eventualy I know it will happen. I wonder if its because they are F0's? They come up to the tank when I feed them so I know they are use to me. Guess I'll keep trying to look for the magic labito food for them.
(no pun intended),
