If they are around 5 days old, they may well have ventured out of the cave and have returned of their own accord.
As Des says however, the male could be young and inexperienced.
The best bet would be to ensure that there is enough food about for them to scavange. Make sure you remove all uneated food the next moring if you feed tham at night.
The fry are usually safe from other adult fish, Ihave only one male that causes any problems and it is quite unusual.
If the fry are still in tehre, then they will probsably come out at night when the lights are off to feed.
If things have gone wrong and youhave lost the fry, try not to be too dissapointed, it happens quite alot with first spawns. If it is your first spawn you have done well to get any fry at all as the eggs are often unfertile.
You have done exceptionally well getting them this far so well done.
We will all keep our fingures crossed.
Oh, one last thing, if you have sand as a substate, make sure the top surfce layer is always kept hoovered, as I have found fatalities increase if the tank substrate is not pristine.
