It is possible they had been there longer but that was the first time I noticed the female didn't come out for food and the male was hovering just outside the cave. Tank has three tiny bns in it but thats all. Tonight the male is eating but the female seems to just be hovering mostly in the same spot, every so often she dips head down towards the ground. I didn't know if kribs could move eggs or not. She's not leaving except if the male comes over. Can't quite see what she's doing, theres a rock in the way!
