Clownfish with varied black spots

[kbnh]

Not sure what this is, my clownfish has been in there for about a month and a half and I just saw this pattern on him now, he definitely did not have it before, I’ll try to get pics in white light soon but I have a screenshot of it without spots and a couple of pics with spots

Nothing new added to tank, had bought him and other fish pre quarantined.
Parameters are
Sg 1.026
Nitrate 5 ppm salifert
Phosphate .07 hannah

Its called hypermelinization and its from getting stung by corals either rubbing up against it or the fish thinking the coral is a host.

Pics are extremely dark to confirm anything but as mentioned, often stings from anemone or coral causes this which has no impact on fish and will subside until gone
