Biggest Eel For A 120 Gallon

[kzimmerman]

I used to have Missy Eeliot in a 75g, she was fine but not out much. When I got the 125, suddenly she was out exploring the tank all the time, so maybe the 6' tank would be better. I could have something bigger in the 125, but it's certainly not big enough for tt or fire eels. I'm not aware of anything that doesn't get bigger than the tank, but is still a bigger eel.
