Cause of dying fish?

[marineang]

I know some reefers don't get upset over losing a fish..I do though. I've been really lucky and haven't lost one in my 29 for quite a long time...pretty harmonious. For the first time yesterday, I noticed my canary blenny looking slightly emaciated which I found odd because I've seen him eating consistently (or so I thought). Today he's clinging to the back corner of the tank, looking even more emaciated and pictures don't really do it justice but where he is clearly sunken in, he's got a lot of redness there - almost looks bacterial infection-ish. He's not gilling hard, just the opposite, really slow. I did move a few rocks today and dropped one when my maroon clown bit me, it's crossed my mind that I might have injured him - though I didn't see anything of the sort.

My levels are ok, he's never been picked on. Damnit I just feel badly - I love that fish.

Any thoughts? Is recovery at all possible?

I'm one who hates loosing a fish... Doesn't help that Kim names them so we get even more attached... As for the possible of dropping the rock on him/her by accident does the fish swim around differently? And if you did drop it on him/her that's not good

Also if it's possible I'd put him/her in QT and treat for bacterial infections because if you did drop a rock on him/her and there is visible redness it could turn into a bacterial infection. Just what I'd do, of course if you don't have a QT that limits what you can treat the tank with for meds...
