Grey spots on my fish!

I have 3 parrot fish in a 60 gallon tank. two are doing perfectly and one has grey smudges on it. they are not spots, but actual smudges. it almost looks like its dirty. It also hides a lot. other then that, it seems happy and eats well but i dont know why it looks different!

spots

black spot disease??? these smudges occur when they are stressed, that could be lots of things, poor water, illness, cure the problem and the smudges should clear up

Re: Grey spots on my fish!

At night with the tank lights off, shine a flash light onto the fish. See if it looks like gold dust on his body, If it does, it's probably velvet.
