You shouldn't need a public poll to know what is morally right. That seems a little strange doesn't it?
If your dog gets fleas and somebody on the internet tell you to boil him, are you going to do it based on polling a group of folks who like to boil dogs?
Nonsense.
So let's look at it this way, say the person is new and like all of us when we were new tend to overreact to things...nothing wrong with that.
So, say Dunnman leaves the fish alone and the fish lives a long and healthy life.
OR
We can start subjecting the potentially healthy fish to exposures to freshwater tortures, medications that will cause permanent liver damage, garlic seasoning etc etc.
If it wasn't sick before...
The reality is, if the OP's little fishy gets ich or velvet, they will know it, at which point they may want to try harsh treatments or medications to save the fish that may or may not work, which is besides the point as that has not been shown to be the case.
I actually encourage you to start a poll, if nothing else, I'm sure it will treat your ego well.
The OP never did mention the size of tank, but based on the information we do have, it just looks like a bored, lonely or bullied clown hanging near the only thing in the barren tank that resembles something that might be found on a reef and may host it. A security blanket if you will.
So we will wait and see in the morning whether the fish stays near his spot or floats to the top.
That is if you guys don't kill him first, lol, don't do it just to spite me.
What I would recommend to Dunnman if he/she is thinking to medicate, is to figure out arrangements for a hospital tank, which includes a plan of how you are going to cycle a tank in that short amount of time, or have lots of extra water ready to control ammonia should it rise...
That way if in fact your fish does have something, you are prepared treat and house the fish for the 3 or so months it takes before you can return the fish to the display.
Be mindful of your equipment exposed to medications, don't contaminate you main tank. Soak anything exposed to medications in some vinegar and give it a good wash before returning any equipment to your reef tank.
Good luck
