Never seen this before

[sergifed91]

I have a yellow eye kole tang. With a black streak on its tail. I just noticed it. It is eating like a pig. Just concerned as I just went through a 90 day qt and follow of DT. Treated every fish with coppersafe for ich. Now it has this black streak. Has anyone seen this before. Neat picture I could get below.

I've seen that before - not sure what the cause is, but it isn't from any contagious disease that I know of. It's basically melanin deposited along the fin rays.

Nope - it may just grow out, but that will take months....like if you get blood under a fingernail.

This wouldn't be related to a lack of Nori in its diet.
