Is this a disease on my clown fish? Marine Valve? HELP!!!

I QT my fish for about a month and these mochvinchi Clownfish has been in the main display tank for a few weeks now and I started to see them rub on my glass scrapper and spotted these dots on them. I’m not sure what they are or if it’s just damage from something else...?

They also have these black dots on them at the bottom of their bellies and I’m not sure is that worms in them or if they are normal... it’s not a bump but looks like black spots.

Tank parameter are below:
Salinity: 1.025-1.026
Temp: 77F - 80F
Alk: 9.1 dKh
Cal: 405 ppm
Mag: 1290 ppm
Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate:12 ppm

Below are photos and a link to a video of the marks and the clown rubbing on the scraper. Both clowns are rubbing now and than on the scraper. If I remove the scraper, they will rub on the rocks from time to time throughout the day. They are eating tho, 3x a day on pellets and frozen mysis.

First off great job documenting all this. Makes it really easy for people to give their opinions/advice.

I think the spots might just be stings from corals in the tank? I’ve seen it online before but never experienced it on my clowns. Also, clowns are pretty weird and mine rub up against all kinds of stuff and are perfectly healthy.

Thanks for a quick reply, you think it’s the anemone stinging the clowns? They have been hosting it for about 3 weeks now and I just notice these actions recently within the past 2 or 3 days...

Are there any other corals in the tank? I guess it could be the anemone, but I’m not confident saying either way.

Watching the video again, my clowns spaz out like that sometimes too. I wouldn’t really worry about it. Some people’s actually host things like the mag cleaner and will constantly rub against it.

I have torches and frogspawn corals with sps and zoas in the tank also. The clowns never go near the torch or frog spawn that I have seen tho.

Occasionally anemones can sting clowns especially in the first few weeks of hosting. Behavior-wise the clowns look fine and probably better to just let them be, maintain good water parameters and not induce any uneeded stress.
