Intresting hitchhiker

[Electric eel]

I have what I belive is some type of eel. It is about 6 to 8 inches long, purple in color. I have been unable to find any information about it. I had a fresh water rope fish once that looked similar (not in color) It is very hard to get a picture of it, I have had it for about 3 years and only seen its full body once. If any one know were I might find some information about it that would be great.
Thanks James ( I will try to post a pic)

Maybe a ribbon eel. That's one cool hitchiker though!
