Eels that are left in a bucket of water will die!!! They need to be in a airatored live well or left dry.
This bucket if left in a cool dry place with ice every 24 hours will keep 24 eels moist and alive for 1 week or longer!!
I have had as many as 3 dozen for a week with only losing one eel!!
The covers are called Gamma Seal, they can be found on the net easy by doing a search on Yahoo, or clicking this link

There are a bunch of sites that have these covers from as little as $6 each up to $10 each, so search them out to find the best price!!
Good Luck!!
