Thank you all very much, It is indeed an American Eel. I call a LFS to ask about trade in credit and every other reply he said " Do not Release it" After the 4th time of Saying "I know, I was not planning on releasing it I knew better", I replied, "Listen you have convinced me, I'm going to put it in the pond here at my apt complex" and hung up. Relax I will not, I have found a co-worker with a 65 Gal tank who is willing to take him and give him a good home. He is also aware how big they can get and will upgrade tank as needed.
PS I can't wait to get a house so I can get a large tank!!!!
