Are these blotches disease or injury on Kole Tang
He’s been in my system for 8 months after being quarantined. No health issues and has been an active fish in my DT.
Recently these blotches have shown up and I’m not sure what they are. All I can think of are flukes or bites from another fish. I have a blue jaw trigger and lemonpeel angel that could be the culprits.

Possibly from the trigger but I would assume you would see more of a open wound if that was happening. Are you running carbon? Reminds me of hole in the head and HLLE

Yes, I'm running a carbon/GFO mix.

Bites would likely be more in the tail/body areas.
Facial injuries would be more in line with him trying to eat something that put up a fight. This would, however, fit a predator better than an herbivore. Carbon induced HLLE would be my first suspect with a Tang. Sent from my XT1254 using Tapatalk

I've never heard of HLLE before. Google says it stands for "Head and Lateral Line Erosion" is that correct? If so, how would carbon be causing some type of ailment? I can't certainly stop the carbon but at the risk of Nitrates increasing. I have a fish only system and as of Sunday I was at 28 ppm.

Tests have shown that carbon dust in the water causes HLLE with a number of fish families. Tangs are among the most affected.
BTW, how does carbon help much with nitrates? It would have to be in an anaerobic environment to do anything. Though in such a setting it would rather be unlikely that carbon dust makes it into the water. A better way to fight nitrates would be vodka or vinegar dossing together with wet skimming.

I did read that about the carbon dust, which apparently is more prevalent in cheaper carbon products. I'm using the BRS Premium ROX 0.8 carbon, which should have little to no dust.
Based on the pictures of HLLE I have seen these blotches don't really look like it. This would leave injury from another fish as the most likely cause. The funny thing is I have never seen the Kole tang pestered by any tank mates and if anything he's the most aggressive one in the tank. I guess I'll take a wait and see approach. I have another fish in QT so once he's done in a few weeks I might pull the Kole tank and put him in a hospital tank and see if I can get the wounds to heal. He's still active, eating well and showing no signs of any other ailment.
