What’s this line inside the fish

[Fishie]

Hey guys, just acclimating some wrasse into my DT and noticed this line like thing inside one of the wrasses... I couldn’t see this in the QT but the DT Light shines through the wrasse and shows this in certain angles.

The fish itself is very active and eats everything .

What kind of wrasse is it? Could it be a cut or injury?

red margin female...its not at the surface level...you cannot even see it until i saw the light shine through it's body.

and it's the most active and curious of the lot

Could be normal for that species @evolved @eatbreakfast can probably confirm

A photo under white light would be helpful
