I always remove my eggs, I don't want any more babies. Plus the eggs make a nice treat for my albino african clawed frog in another tank. My pair hasn't ever bitten me, although they seem peeved and confused when I take out the flower pot they always spawn in/on. Mine were successful with their first try, and didn't eat any of the babies, didn't spawn again until they first brood was gone. Then they spawned within a week. I thought the stress of having their babies suddenly disappear might slow the process, but they were at it again right away. The first time they spawned, the female ate several of the eggs. I don't know if she did this before or after they were fertilized. I read somewhere (maybe here on cichlid forum?) that they might eat eggs that didn't get fertilized to prevent fungus from growing in them and spreading to the good eggs. I don't know for sure if that's what she was doing, or perhaps just reducing the size of the spawn, or maybe she was just hungry. But she and her mate were very protective when it came to the babies. The final total from that brood was 43. That was after 1 move to a new tank, elevated ammonia in their tank due to overcrowding while I searched for a home for them, and the final netting for transport to their new home (one fish jumped out of the net onto the floor, and dispite my efforts to save him died soon after he was put back into the transport container). Anyway, that was my experience so far.
