Help my Blue Eyed Tang!

[Modge]

I’ve never had any parasites in my new tank but made a bonehead move and put some LFS macro algae in my sump a few weeks ago.

I just noticed a single discolored spot on “Gorgeous”, my 4 year old daughter’s Blue Eyed Tang. Have had it for about 6 months along with that Scopus in the background. Now that I’m Looking more closely at the Brown Scopus “Charlie” - I notice he has a lighter discolored spot where his body is very dark.

Fins and gills look fine - other tank mates (13 fishies) all look fine.

Tangs run the tank and don’t get nipped.

The white specs in picture are floating debris and micro bubbles.

Could be flukes (a simple and harmless fresh water dip can confirm? Or it could be lympho, also harmless. Just my opinion.

Here’s a better photo - right above her pectoral fin.

Behavior is fine and normal. Spot almost has an indentation to it.
