Kribensis Breeding?

I just got a male kribensis for my two female kribensis. Later that day i saw my biggest female trying to get the male attention. Now she's hidden in a rocky cave and hasn't came out especially during feeding time. The male is around the cave going in and out just for food. Is it possible that she caring the frys inside and male protecting?I can't see nothing because it's so dark inside.

Never mind,just checked in the cave,but no frys.
BUT i than checked the cave inside ceiling and found eggs
