My kribs spawned, the fry hatched (about 75) and the all but 3 disappeared the second day. Now 4 days later at least 10 of them have reappeared in the cave! I don't think the parents moved them as they never were guarding another area. Plus why would you move all but three? Because I have larger pebble substrate, not the recommended fine gravel or sand, is it possible they escaped the cave an fell in between the pebbles only to reemerge a couple of days later? When they first hatched, the parents were constantly catching the wrigglers the fry in their mouth as they approached the end of the cave and spitting them back into the rear of the cave. I just don't get what is happening.
