Guppy is flashing/scratching - parasites?

Nireht

AquaClear 50.

Appears he has a gill sticking out, skin loose on his back, looks like he's missing scales, doesn't swim right, kinda crooked. He has a voracious appetite tho.

Instead of swimming horizontally he swims diagonally, and slowly.

Amazing, a true Super Fish. I have that type of filter, how did he get thru the slots?

Nireht

I have a pre-filter sponge. So I don't know. I think I must have dumped him in when pouring tank water into the filter to get it going after turning it off perhaps. That's the only explanation.

Ok, so he was inside the filter box itself? If he'd gone up the tube he'd have to have gone thru the pump past the impeller to end up there. Doubt he could have survived that trip, but who knows I guess fry make it sometimes.
