Red Marks on Green Chromis
Purchased 5 green chromis about 2 months ago. Today, I noticed red marks on one of them. Hours later, he is staying near the top and breathing heavy.
Disease or aggression? Something else?

Parameters are all perfect. Tank is 50 gallons and also has standard clownfish, tube anemone, and torch frag.

Hopefully the photo helps. No signs on other fish. Any help would be great!

Hard to tell.
I'd say disease... Because for having them for 2 months that guy looks quite thin.

I’m going to also go with some sort of skin disease or infection.

Work on improving the biodiversity in your tank. Competition is the best defense.

I see this post is a bit old, but for anyone else seeing this I had a similar problem with a blue chromis a few days ago and the infection spread to my other fish. The host chromis and a clown died before I could do anything about it. Then I dropped some Jungle Fungus Clear into the tank and it seemed to stop the progression of the disease. Now the fish are getting better, minus some loss of tail fin length.

Update: the meds just slowed the disease. I now have 100% loss. Note to self: quarantine for a few weeks before dropping new fish in the tank.
