Black dots? Am I paranoid?

[stricknine]

One of my occ clowns is getting black dots on him (few on head and near top fin). Doesnt look like a growth, just colour change. Is this a sign of something? He seems ok.

Thanks.

Do you have zoas in your tank? He's probably being stung by them if so. No big deal.

Yes, zoas and euphyllia. Shouldn't be a problem?

Black spots are often caused by coral stings, keep an eye on it, eventually they should fade as the clown gains immunity to the stings.
