your profile says 75g? IMO SFE's are overrated and there are alot of better looking species out there. the zebra might get too big for a 75g, 125 minimum is best IMO. If you were gonna do an eel in your 75g, I would do one that you REALLY Like.
I have 2 75g's.
one has a fimbraited moray and a chain link moray.
the other is my spotted morays tank.
if you really like the zebra moray, I would get that one and pass on the SFE...
