Mandarin sluggish and not eating, Help!

[Vagabond]

Danny - He is still nice and plump, however this is going on the 4th day of this behavior and I am quite concerned for my favorite fish .

If the little guy was stung by the anemone anybody have an idea how long it might take for him to recover?

As of today his colouring is still excellent and he is alert but just doesn't move around much and still won't eat. Perhaps I will soak his mysis in garlic to see if that will entice him to start eating again.

Any other ideas to help him recover are welcomed.
