Please explain this one

I would just leave him alone, try not to further stress the fish.

I, as with many, believe ICH is always there. This is an ongoing discussion, all of us with our own point of view. I don't worry about quarantining. I purchase my fish only from LFS that do their due diligence in treating, feeding and only letting the fish go for sale, when ready. These stores do exist, and I have only ever lost one fish due to disease.

Sorry to hear about your beautiful fish, I think it will be ok.

Get a UV light if you don't want to risk all you fish getting it.

Regardless whether you believe ich is always there or not, it will more than likely show up in your display tank despite your best efforts. This certainly doesn't mean quarantine procedures are useless but ultimately when you're dealing with something as common as marine ich, which can be introduced without fish, at some point you have a significantly good chance of dealing with it.

My advice is to accept the fact and not attempt to fix it. Leave the fish as is, in a healthy system with healthy unstressed fish ich will not flourish to the point of casualty, rather it will come and go in a fairly harmless manor. A UV sterilizer properly designed and sized for the aquarium is a good investment. While it will not eliminate ich completely and using it all the time is not necessarily beneficial for reef environments using it periodically as needed will help prevent large outbreaks of ich, especially when stresses are potentially high which is typical when new fish are introduced.

IMO, Ich is like the common cold for fish. If you get stressed, you get sick. If you rest up and each well, you get better. I don't think you can completely eliminate ich from your tank. After a mystery disease killed off all my fish a couple of years back, I let the tank sit fallow for 3 months... if there was ich, it should've all been gone by then. I quarantined my new fish for 8 weeks, all signs were good, so I put them in. Bam! Ich. WTF? Seriously? But after a few days it went away.

I'll only attempt a dip if it's getting really bad and not showing any signs of going away on its own. My Coral Beauty get small ich spots from time to time. I don't worry. It goes away in a couple days.

IMO, quarantine is more for the nasty stuff like velvet and worms.

Good stuff, thanks for the feed back. He is swimming around and enjoying life, also eating lots. I mixed up a batch of raw shimp and fresh crushed garlic, I will feed this for the next little while and monitor him.

use a garlic concentrate mixed in when thawing food. This way the food will be soaked with it, he may not take the minced garlic

Sorry, but I disagree about not having LR in a quarantine.
ich needs a host to reproduce. without it, it will die.
after feeding on the host, it drops off and it becomes a Trophont.
it will stay in this stage regardless if there is live rock, sand or nothing at all.
it then hatches typically within 6 - 10 and must find a host within 2 days to survive.
not sure what Ken meant by Ich can survive on LR when not on fish.
if no fish host, the ich dies within 48 hours after hatching.
I would highly recommend that you use live rock in your quarantine.
otherwise you could potentially deal with spikes in ammonia and so forth.
Chances are you probably had ICH in your tank from before.
Or the Harlequin had it during the quarantine and you may have missed the signs.
like others have said, I wouldn't stress out too much as ich is in most tanks and will tyically not kill a happy, healthy fish.
trying to catch him will stress the whole tank out which will increase the chances of others starting to show symptoms as well.
just want to clarify that garlic is not a cure, it will just increase the fish likeliness to eat which in turn increases their immune system.
eating fish are typically healthier fish.

good luck
