I have 4 clown fish and all 4 are getting little black spots on them
Now I know what white spots are but these are very black round spots any ideas???
Do I have to worry? all else seems fine

I had the same problem on my two Oscellaris clowns, but it is going away now. I think the problem was related to a recent death of caulerpa and decline in water quality. I just put the skimmer in full blast and got rid of the rotting caulerpa. I never did find out what it was or how serious, but I hope you have the same luck I did.
