Noticed a white spot on one of my Ocellaris clownfish ~10 days ago. Looks like it’s gotten slightly bigger. Can’t tell if it’s a coral sting or injury that will heal or something I need to treat. Any guidance would be appreciated
For context, have had this tank running for 5 years. Two clownfish and assorted soft & LPS coral. Haven’t added anything in a long time. Latest additions would be some snails/crabs from reef cleaners ~6 months ago, so suspect no new disease has been introduced
Other piece of info, about two weeks ago the clowns started kicking sand away from a spot under the rocks. Unclear if it’s almost breeding time or what’s going on but this is a recent thing
