Thursday my midas blenny didn't come out to eat which never happened before so I found him in a rock. When he came out he wasn't swimming right. He was almost upside down at times. Then laid on the sand (something I never seen him do) and didn't move when a nassarius snail come up to him. He stayed hidden and didn't eat Thursday and Friday. I didn't think he was going to make it much longer. Saturday I dosed tank with prazipro just to try something since my qt is in use. Sunday evening when I got home he was actually a lot more active but would only eat one or two pellets of food. He hasn't eaten but only a couple bites everyday since Sunday.
He also has had these I think see thru spots on his dorsal fin ( I guess it is) and is skinny. Anyone know what's happening?
