It looks like a perfect circle, almost like a stamp. He had it in a different area and it went away and now he's got it again here. This is the only spot, it's not on the other side of him either.
It's hard to snap a photo of him because he moves away from the glass when I go near it so this was the best I could do.
Any ideas on what this could be?
Water params are as follows:
Ammonia 0
Nitrates 0
Nitrites 0
Ph 8.2
Salinity 1.025
Phosphates 0.02
He's in a 90g with a a 30g sump
Starry blenny, allardi clown, lemon chromis, some corals.
No anemones. No shrimp.
He isn't rubbing on any rockwork and doesn't seem irritated at all. He eats normally, nori every day and a mix of spirulina, brine, krill, mysis (different every day for variety).
If you need any more info just ask. I've google and looked I cannot find anything similar. Thanks!
