Tiff, AFAIK, most discus breeders I've known pull the fry (or parents) after a couple weeks at most. The fry feeding on the parent's slime coat can be hard on the adults after a short time & most breeders want them to spawn again & produce more babies! New parents, like many cichlids, may eat fry when they're ready to breed again...or I've heard of parents being so into fry care that they don't eat well & that's not healthy either.
