After being surprised upon my return from vacation by seeing fry in my N. Pulcher tank, I spent some time observing this afternoon. It seems they range in size from about as big as the head of a pin to 1/2 inch. Is this the result of 1 spawn? Do I need to do anything special? It seems they are doing fine being left alone. I did crush some sprulina flakes, mix them with water and put them in the general direction of where the fry are hiding with a turkey baster. The fry seemed to love it! Sevedral even ventured out of the cave to get at it. Thanks in advance for any pointers or advice.
