Black spot on clown fish

[maiv_2000]

Hello,
One of my clown fish that I have had for about 4-5 months developed a dark spot about 1/4” seemingly overnight this past week. No other fish has one. I can’t tell the color of the spot. She’s acting and eating normal

I have attached a video

I’m concerned about uronema

I have used reef medic for 2 wks, twice in the past 3 months because i lost an entire tank of fish 3 months ago in another tank and most of my fishes came from the same store. All the fish that died in the other tank did not have a single spot on them.

Any thoughts?
Thanks.

1. It would have been better to post this in the “fish disease diagnosis and treatment” forum (don’t post anything about this there now.)
2. Could it be hyper-melanization?
3. #fishmedic

I can't see the video (YouTube works best). However, the black area looks like it could be from an injury - is it getting better/worse/staying the same. Any other symptoms in other fish, etc

How did you get the r2r research badge?

I did some research on ammonia in live rock - and proposed the research forum for others who want to design their own studies/research. .

That's awesome how do you exactly post research onto the research forum? Ive got something I could put in there.

If you go to the research forum - you can see the guidelines and recommendations of how to do it.

Do you have any stinging corals or anemones. That does look like hypermelanization to me.
