Oh well there's always next time. I know with my original pair they had to try about 4 times before they finally got it right in the end. I'd give em another 3-4 tries before resorting to separating the eggs from the parents. Personally I like to let the parents take care of everything but sometimes ya just end up with bad parents and you'll need to separate the eggs from the adult asap. If ya have a hang on breeder box I'd keep it on hand just in case they just don't get the parenting down right. The breeder box just makes it easier to protect the eggs/fry while keeping em in the same quality of water as they were laid/born in. Another thing I used to do was add in a pile of rocks or fake bushy plants in so the fry have somewhere to hide from the parents. Sometimes it works but sometimes it doesn't.
