bump near laderal line

[Baby Damsel 219]

I have a tiny green chromis, he is a fish out of 6. all very young not 2 inches. very fat and thick/ healthy,so I thought one out of the 6 has a tiny lump under its d line. Doesn't look like bacteria eats and swims but looks a little dark hides once in a while can get a clear pic but this is a great discprition.

Without any pictures or information we can’t really help. How big is the tank? What other fish are in there? How long ago did you get the fish?
