I had an eel about a month ago and gave it back and it was in a 75 gall. Honestly, it hid most of the time and only came out when time for feeding, and it ate, ALOT! And grew 2 inches in about 2 months. (11 in. when taken back) I did some research and found that my 75 was not big enough for it, so your tank would not be a good home for it. Also a messy eater, and cant or shouldnt have cleanup crew with it (they make nice snacks later on).
