Do you have snails or something for "cleaning" crew in there? They're useful in these situations. IMO their wastes aren't as bad as dead/left over food thus can reduce the need of water changes.
As much as I hate saying this.... sorry but prepare yourself for a total lost. Your fry doesn't sound healthy enough. Maybe this was why daddy ate them (not sure). A good water change may boost their condition - enough to make them eat. Just don't give up on them and keep trying to feed them. Remember to siphon out any wastes.
>.< i hope that even one of them can survive, ill try your advice, i dont have snails or gather fish that will clean the waste, im thinking to add cory dora in their tank, are they compatible??
