Kribensis breedin question?

I've bred kribs many times. They watch us as closely as we watch them, maybe more closely. When they saw you looking at their eggs, they moved them. This is what happens every time when you get a good look at the eggs or fry. 100% normal!

That they are hanging around a pit is proof the eggs or even newly hatched fry (wigglers) are in one of the pits. Don't look in the pit. If you do they will move them again and try to dig the next pit deeper. They are trying to hide the eggs or fry from you, so if they fail, they will take more risks each time, making the pit walls steeper and taller. Very often those desperation pits will collapse and bury the eggs. Watch the tank from a distance. Stand far away with your camera and zoom in with the flash off just in case you are tempted to take a photo. Once the fry are free swimming, you will see them being herded around by the parents. Usually the female is closest to the fry and the father circles farther out, guarding the fry from other fish.

Get some microworms and start hatching baby brine shrimp. Add some Java moss to the tank, just drop it in, in small pieces that fall where they fall. This will provide microscopic life on its surface for the fries' first foods and provide hiding spots for them.
