So I had a 12" snowflake eel that I think jumped. He was in a bare bottom tank with a couple of pieces of PVC. I was cleaning a bunch of tanks including his that are in a clownfish grow out system. I wiped the inside of the glass and he was not happy, he was out swimming everywhere . I went to the next tank and looked back and he was gone.
I searched everywhere on the floor. But these thaks are in the basement close to some utilities so lots of stuff around. I couldn't see a body on the floor anywhere.
I pulled all the rock out of the sump to see if he fell in there, and nothing. I even looked in all the piping in case he went down the overflow, which the cover was off while I was cleaning. Checked the filter sock.
The only thing I can think of is he is still hiding in the rocks of the sump if he did jump and fell in there. Or he landed on the floor and crawled to an open floor drain about 5 feet from his tank.
