Eels for beginners?

[spencerC]

Okay so as you might already know from my many posts of late
(sorry, but thanks for all your help guys )
I am getting a 75 gal marine set-up with very very good filtration (Marc [superfudge] from Hidden Reef is doing a custom sump system for me with plumbing and everything), and i plan on getting a very good skimmer.
Aka, i will probably be able to handle the extra bioload from the eel.

I would LOVE to get an eel for my fish only (probably for the first year, anyway) aquarium.
What would you say is the best eel for a beginner?
And what would i NOT be able to also have in my aquarium with this ideal eel?

I'm worried about
a) size (not too big for 75 gal w/ live rock)
b) eating my new (and likely small for a while) fish.

If there aren't any that wouldn't eat a small fish, i can probably wait a while for the fish to catch up in size, but there must be one?

Thanks guys!
It sounds corny but i don't know if i would be able to do this without the help of so many intelligent aquarists
