ick

I have had good results in the past with crushing fresh garlic on a piece of nori and soaking it in the oil.

Ich usually isn't a problem if you have a healthy tank, garlic does also seems to help. I wouldn't try to catch him to QT at this stage, the stress on a fish already with ich would likely kill him. I've had the odd fish with a few spots on them that just disappeared in a couple days nerer to be seen again without doing anything for them at all. I also wouldn't add any type of medication into the DT.
