The eggs are very small and dark in color at first glance can easily be mistaken for a dirty spot in the tank. How big are the parents? My first pair started laying eggs at about 1 1/2 inches the second pair started not too long after that i usually get about 40 good fry from each spawn so far. I remove the fry after 4 weeks and there is usually more eggs within 3 days or so. My only problem is I am running out of space for grow out tanks. Got 5 spawns in the last couple of months from 2 pair
