Anyway, I noticed that this new guy, Fugi, had a whole bunch of black spots stuck all over his body and some were falling to the gravel as he slid up the tank. At first I thought that he must be sick or something, but when I did the water change, I noticed that there were thousands of these "black spots" all over the gravel floor. Have I fallen off my rocker, or are these really snail eggs? I think I did a pretty good job getting them out of the tank, but should I expect a snail epidemic?
