Mixed Eel Tank?

[CuttleKid]

I have been wanting to set up a FOWLR tank since I was a kid. I have had several reef tanks and I currently have one reef tank and i am looking to upgrade. Now that I have some graduation cash I am wanting more and more to go get a tank for my parents basement hopefully soon to be my new room. I have always loved different and out of the ordinary tanks. I have been doing a lot of thinking and I definitely want a mixed eel tank. I saw this special on Nat geo Wild called morays aliens of the deep and have been hooked on them ever since. I want to create a replica of a reef wall with multiple morays popping their heads out of their own den. The two tanks I am debating about getting is a 180 or a 120. What I'm thinking about for a stock list is the harder to get Japanese morays like the dragons, Yuris and Kidako morays and any other that may become available.

Please excuse my newbish questions. I have kept eels before such as snowflakes and ghost ribbon eels but never any of the real larger more expensive species.

My main question is will this be possible?
Will multiple eels Be comparable?
Any input/advice will be much appreciated

Thank you

you can keep different species eels together, generally speaking try to keep Echidna eels separate from Muraena or large piscivore Gymnothorax. It really depends on which species you do end up getting. I've generally had success mixing species, with the only problems coming from gambling on trying to mix specimens with too much of a size difference.
