I believe fire eels are the biggest of all the spiny eels, even bigger than tire-track eels.
I had a peacock eel once (which is the smallest of the family) and he was an EXTREMELY picky eater. It's very hard to get them to eat anything but live worms sometimes.
The other things in your tank should be fine until they are able to be eaten by the eel, but i've also heard that certain eels won't eat even small tankmates. They are very peaceful fish either way.
They love to be hand fed, and will also come sit in your hand when small.
