No shark species will be able to live in a 180g long-term...they like LOTS of room to swim and get much bigger than 2 foot...
& the moray eels you're interested in will eventually get over 3 foot and at that size, they won't be very comfortable and will need a larger tank...you gotta take into consideration how much of your tanks volume is consumed by the rocks and what not. The rest of your stock sounds great though.
