Eel Tank Experience
Eels will change color if kept in a fish tank or light colored buckets and it takes a long time to turn back to black from green.
I wonder whether it matters much to the fish.
I read something about Tuna guys using clorox to whiten their eels.
2 reasons. One is to stand out in the green colored water of the canyons and 2 that they are easier to handle.
I use one of those scotch scrubber pads to handle the eels, works fine.
Or some sand if available, a little ice works well too.
