Large Black Spot on Brsitoltooth Tang?

[Reefdaddydave]

Hey all,

Having a hard time identifying what this large black spot on the side of my Bristol tooth Tang is? It's large and kinda extrudes a bit from the side of his stomach. It seems to have grown in size.

The fish has been acting pretty normal, eating okay.

It leads me to believe that this might be some sort of parasite? It almost looks like there is a black squiggles inside, which could be a worm parasite?

How do you treat this?

Looks like post injury and shaped like that of a nick or scuffle with another tang
Should heal on its own but in case needed, secure some seachem neoplex or kanaplex to be used in quarantine

Agreed - looks like a healing injury from another tang striking it. At least there are not any highly communicable diseases that would look like that.

Yeah I don't think it's an injury. I've been watching it and it has grown from a small black spot to now a larger black spot. The fish is also sweeping at the sand bed to try and rub it off. It protrudes out a bit too, like a black zit or something.

He's also the top dog in the tank, nobody picks on him. He's the bully of the bunch.
