Yellow Tang Fin Rot?

[ReefKeeperAiden]

Hey all, got a yellow tang about a month ago and recently he has been missing a little part if his dorsal fin. He's in a 120, parameters are spot on. Only tankmates are 2 clowns, firefish, randalls goby, and a green chromis. Dont know what is causing this. I started feeding nori very often and feed frozen and pellet more heavily for now. :angryfire:

Hard to tell, but looks like it could be the beginnings of HLLE.

HLLE usually starts with small pitting around the eyes/face. You'll also notice the lateral line being more pronounced when it advances more down the face.

Where you always feeding lots of nori or is that a recent thing? All my tangs eat just nori. One of my tangs will sometimes eat pellets, but for the most part they're eating nori.
