I have an Ocellaris Clownfish (Wild) that I have been keeping in a 24 Gallon Nano Cube (he's been in the tank 9 months now), and yesterday he started to develop little black dots all over the non-white portions of his body...kinda looks like sunspots, was thinking it might be Black Ich but he doesn't have any spots on the white portions of his body and he doesn't seem affected by it and is as playful and hungry as ever, none of his tank mates exhibit this...any help in identifying this condition would be appreciated...thanks in advance.
