Help Diagnose? White spot on Tang dorsal fin.

[Jontan423]

Tang is healthy and fine, normal behavior, just unaware what that small white spot is... Want to be able to treat if something serious.

That looks like it is possibly an injury, not a primary infection. However, some background information is important to know. Here is a post that outlines some of the information that is helpful to know about your fish and the tank:

Hello thanks!

It is a 180 gallon reef. Been established for 4 years now, the Orange shoulder tang was bought from an lfs about a month ago. The dimple was there but it wasnt white like it is now. I feed mysis and nori in two small feedings a day.

I was thinking injury.

I've had injuries appear and would start to freak out... ick.... Hopefully it will go away in a couple days. Doesn't look like the nasties.

Tanks like to squeeze into rock work at night probably just a scratch

My orange shoulder is like a (friendly) bull in a china shop, constantly knocking into stuff, flipping over frag racks, and just generally busting up stuff in my frag system. Small lacerations were common.

I was just more concerned of it being hlle because I've never had that happen before so I'm not to sure how to diagnose the early stages.

The guy can clear some algae better than anybody though. Even green turf he would bash through. He is very happy now in a 12" tank I helped set up locally.

That's not HLLE. As long as the lesion doesn't grow, or start up in new spots, you should be o.k. The other issue is - if this is a bacterial infection (likely) you would need a treatment tank to dose antibiotics in.

A nip?
A mistake?
I would expect that to heal in good conditions.
But keep watch.

Boys will be boys. Orange Shoulder tangs will be Orange Shoulder tangs. Definitely one of my favorite fishes. Beauty, utility and personality.

Until @Jay Hemdal says you gotta do something about it just keep feeding the beast well and relax. When he says "act now" then you do so.
