Dark spot on clown

[Hsquared]

What is the dark spot on the white part close to my clown’s head? Acting fine but it is on the other side of him too. I have a dottyback that seems to think the entire tank is his. Could it be an injury from him?

how old is the fish?

Naturally occurring marks.... like us having various spots on our skin over time

how old is the fish?

Young. Had about a month. Only about 1.5 inches long. Spots just showed up over the past couple days.

Getting really worried. Clown has not moved from sleeping spot today. I did add a fish last night. Here is a video of spots. They look more red today. I appreciate any suggestions. Really dont want to lose her.

He's getting STUNG by smthg

What coral do you have that has tentacles?

He's probably trying to get hosted by smthg with tentacles and the coral is rejecting him by stinging him.

Probably stung him into being shy.

I have candy cane, zooanthids, duncan and acan but none where he hangs out.

I’ve seen this on my clowns when they were also showing signs of brook/velvet. You may want to treat for possible disease.
It may also be early signs of HITH which I think happened in my clowns as a secondary infection.
