Im on my 3rd batch of krib fry as my other 2 didnt last too long. The babies are now getting big 2months old and the parents are still protecting them with no sign of more eggs is that usual?
At some point the adults will see the fry as competition for space and tank resources. If the fry are pretty much left to their own devices these days, then perhaps its time to move them to the livebearer/loach tank...
But look out for signs of the fry upsetting the landlords/ladies!
