Hi..

he does eat fish.

Okay.

I don't know how long 50cm's is,

~20"

but mine is 18+ inches long and the only thing he pushes
over is a broken clay pot.

Sounds good.

pointed out, keep a tight lid on it After everyone
oohhs and aahhhs over my other tanks, they usually end up
watching the eel for some time.
