ick

[intarsiabox]

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.
