I noticed recently this white spot on the side of my clown. It's only in one spot so my confident it's not ich. It appears to have gotten slightly bigger. No new additions to my tank in months.
Otherwise fish is acting fine, eating, playful. Hoping it's just a bruise or something.
Any suggestions are welcome.
Thanks

Mainly seen in wild caught clowns these are bacterial lesions often a sign of early stage and active brooklynella. Easily treatable with Ruby rally pro and confused with ich. Ruby rally is coral safe and takes a couple of days to start working.

That's not ich. Brooklynella mostly infects newly acquired wild caught clownfish.

How long have you had this fish?
What tankmates are in with it?

This is probably just a minor injury from squabbling with another fish.

I think this is a sting from the anemone - it's not brooklynella. Agree it could be from squabbling - I would watch it for change

Thanks for the information.

The fish is over a year in my tank. I have a mandarin, and a bleeny. Other then that just inverts. My emerald was getting a little feisty as of late. Hopefully it's just a scratch.

Do you see the discrete 3 or so dots - those look like stings. - I don't think its a scratch
