Hey, so you posted a message for me and here is what i have to say. I have experienced egg-eaters before as well and i have tried to respawn them and again they would eat the eggs, even if i conditioned them for a much longer period of time, but i really want that betta's genes so i have done this, i put the male in (egg eater) and he usually squeezes out the eggs and places them in the nest, and i wait till they are completely dont then i remove the male and place another well conditioned male in to take care of the eggs and that usually works, i have only had this not work once so it should work for you. Hope this helps!
