My GT's breed alot and the only thing I had a problem with besides predation was the fry getting sucked up in the filter when they start to swim near it. Some people claim this never happens and I don't know what kind of fish they have but I've had to save fry from my canister filter every time(that would be four times). If you're thinking of moving the eggs Don't, for some reason the female usually moves them one by one to a differant (maybe safer) place I use Hikari first bites for food but since it's more like the consistancy of powder I actually have to suspend a tea ball full to the bottom of the tank so they can get it. The reason for this is they won't leave the bottom for at least a week after hatching, that is until their mother starts leading them around. I forget when, but as soon as they will take it, switch to brine shrimp, they love that stuff. you should have about four day's until they hatch, sorry if it's too much info and good luck!
