Okay I was outside working and came in to fine my midas blenny carpet surfing.......I am not sure how long he was there but he was still alive when I picked him up, not totally dried out but shocky I think. I quickly placed him in the tank and he laid on the bottom breathing heavily and was very mottled colour as he gets when stressed out. I left the room and came back to find he had made his way to his hidey hole in the rockwork. He is in there now and i can't see him at all. He is there though....I just hope he didn't crawl in there to die. He usually has his head sticking out the hole but now he is completely in the hole. So those of you who think that egg crate is safe, think again. A 6 inch midas blennie made it through the eggcrate and out onto the floor. I am suprised the fall alone didn't kill him.....but it is too soon to tell......poor little guy, he was one of my favourite fish.
