I have a Royal Gramma that's been in my 13.5g nano tank for about ten days (along with two Ocellaris Clownfish and a couple of blue-leg hermits and trochus snails). It seems pretty happy/active, darting in and out of the live rock. Parameters are all good.
This morning I noticed a single white dot just below its dorsal fin, about the size of the point of a pencil. I don't see any on the other fish or this one, nothing on their tails or fins. Attaching a pic of it.
It's been there all day, anything to be concerned about or action I should take?
