Gem tang

Can Anyone tell me what is white line on Gem Tang fin both sides?

Maybe I'm missing it somehow, but I'm not seeing a line.

^ same here. The only line I see is a line connecting the dorsal fin spines to the body

I can see a lighter line of dots on the dorsal fin - it doesn’t look like much more than a patterning thing though.
There does look to be a small tear in the fin there, so you could be seeing a response to injury.
Keep an eye out for any aggressors.

The line and tear disappeared the next day
