they are physically everywhere you look, not big ones yet, but babies are everywhere (there are no fish in the tank). I honestly don't know what to do with all those guys honestly. there are a few hundered visible on each wall of the tank with strings of algae looking eggs all around the walls. It is intense. what should I do? add fish? I have been waiting almost 5 weeks now because I had a velvet outbreak and was waiting for it to subside...
