Spot on clown fish head

Did you pull the carbon?

I did not pull the carbon. Only change made was mixing the food with selcon. I don't think that changed anything overnight though.

I'm thinking that marking was from swimming into an object. Not sure what it swam into though.

I know this is an old thread but for others’ information our clown has this and it has come and gone twice. It’s symmetrical, only on the head and in the e act same spot. We thought it was a scrape the first time. ‍
