This happened to me three times with a juevenile clownfish in my tank.

first time, found him in the sump (he was so small he made it through the eggcrate on my overflow and went for the pipe ride into the sump)

second time I found him in the sump again.

third time (two days ago) I found him as a piece of fish jerky behind the tank :(

This is insane. I looked absolutely everywhere, lifted up every rock, moved corals, etc, and its no where

Any chance its in the sump or worse, behind the tank on the floor? :sad:

thats weird cuz i just lost 1 of my clown fish 3 nights ago too. Checked to make sure everything was ok in the morning (which it was), went to work, came home and the little guy just dissapeared. No dead body pieces anywhere, and i spent the whole night checking each LR with nothing.... very mysterious.

I had a tomato clown and just recently 1 Anthias.

I agree Animals can teleport if they really need to

Sory to hear that.Do you use hang on tank filter or protein skimmer? Especialy percula/ocellaris clowns may get sucked by them. I hope i am wrong .

What kind of tank do you have? If it is one of the all-in-ones with the false walls, I've heard of clownfish jumping the barriers into the fuge.

Its been a couple days now.Perhaps you should test your water.If it was stuck inside a hole in the rock and died,it should show a pretty good sized spike on a test kit by now I would think.
