I recently got a gorgeous blue ribbon eel who was very very active when I put him in the tank last night. the LFS
(of course) mentioned nothing about them being jumpers (though I should have done my own research as well).
The lights turned on this morning and sure enough he was active as ever. I came back a few hours later and couldn't see him. Searched the tank and sure enough he was on the floor. Must have been there for atleast 30 minutes! I picked him up and put him in a drum of water I had sitting for a water change later this afternoon. Sure enough he came back to life.
I've put him back into the main tank, but now I need to find out how to properly cover the tank. I've attached a picture, and the lights you see are very hot and strong metal hallides, so I'm not sure how to go about covering the tank, without interfering with the lighting or metaling anything.
ps- i know the tank is dirty, massive algee issues since getting the lights, switching to an RO
