Is this bacterial or a parasite?

[SeaMonkey4]

My tang is in quarantine. It is just over two weeks. Unfortunately on hippo tang in my display tank was in high distress and I had no where to put him so I placed him in the quarantine tank with the new fish. The hippo died by the next morning. I still have no idea why, all the other fish and inverts are fine. Now this weekend the new tang is showing soars. It doers not look like ich to me. The hippo had that when I first got him. But what is this? Can it be Hole in the Head? I treated with LifeGuard by Instant Ocean starting yesterday and it is for 5 days. I just don't know what it is so I am not sure if I am treating him correctly. I am using prime daily. I have a sponge in an aqua clear filter that was dosed with sea chem stability. I did a 50% water change before starting the lifeguard dosing.

The area is by the fins and below mainly.

He is eating and seems happy enough...

Any suggestions? I have not gotten to the one year point yet. That will be November, so I still a newbie (an will be fore some time).

Thanks in advance,
Teresa

What are the water parameters on that QT? Ammonia? Nitrate? It could just be a coloration thing since he's in a low light tank.

"LIFEGUARD tablets with HaloShield® attack a broad range of external fish diseases in saltwater aquariums-- bacterial, fungal, viral, and parasitic. It's HaloShield, a revolutionary non-antibiotic agent, that makes LIFEGUARD pre-measured tablets so tough on harmful disease-causing microorganisms. Safeguard tanks with LIFEGUARD!"

Sounds like woo and nonsense to my scientific eye...I'd stick to known antibiotics that have published and reproducible effects like maracyn plus or kanaplex.

Yeah, IME, anything that claims to do everything can't do anything well. I think lifeguard claims to be reef-safe too. That should be an instant warning. There is no reef-safe ich cure.
