Tang and trigger. Possible ich?

That’s what it feel like it is. There is now a lot less spots it seems.

Velvet comes and goes quickly it’s life cycle is much faster than ich.

Anything wet (coral frag, rock, sand, chaeto, fish, etc) can all bring in velvet.

The black durgeon really does look like it's got velvet going on ...

Can't recommend treating in the display, as copper will be absorbed by rock, and to a lesser extent, by sand. That makes bringing the medication to a therapeutic level - and holding it stable there - difficult. Afterward, you're faced with the challenge of removing the meds from the rock, lest they leach out at some later date and cause problems. You've received some excellent advice on treatment above!

I can't really see the black spots on the tang in the photo - if they're small and sharp, almost as though someone spilled pepper, then "black ich" (turbellarian worms) may be a possibility. Prazi-Pro usually handles them.

If there is velvet in the tank, it won't be sufficient to remove and treat the trigger - all the fish will need to be treated.
