Help Naso Tang showing this. No idea what is this.

I have to quarantine all my fish because of Ich. My Naso tang is showing this white line. Do you have any idea what could this be? Naso looks super skinny.

It is near its tail.

Wondering if it's possibly an abrasion?

One side, or both?

+1 He probably scratched himself on the PVC.

With regards to him being skinny, have you seen any white stringy poop come out of him?

I have not seen any poop. I am dosing metroplex when i feed them.

He doesn't look very skinny in the photo, but that could just be a trick of the camera. The white patches almost look like their typical stress markings. I've had blonde naso tangs that would be almost constantly spotted like that while in my copper system.

X2. They also have dramatic looking injuries that discolor easily as well. Watch for infection and grab kanaplex, metroplex, and furan 2 to have on hand just in case.

Try red nori and blackworms to get him fatter
