are you sure it has been eating what you've been giving it? that thing looks like an aquatic version of nicole richie (well okay your fish is at least much less gross).
what have you been feeding and what did you switch to just now? hurry up with those params. if a fish is malnourished, it will be more prone to stress, so maybe that's what happened? it would explain why the other well fed fish are doing okay.
are you using any food supplements (like selcon or vita-chem)? if not i would suggest starting now, at least for the blenny.
i believe if a fish is foxface stung, it puffs up and the stung area goes red. do you see any unusual lesions or sores?
