I have been away from home recently, almost a month, but i could still go back and feed the fish every couple of days. (Had to leave while they fixed the floors) During that time i noticed my corydoras had stopped breeding. Atleast i dint find eggs anymore, BUT yesterday my cory spawned and i saw what was going on. My apistogramma macmasteri juvenile, the larger ones, were following the cory around and eating eggs as they were laid. Guess they found free snacks.
