saltynay, sounds like you have a great resource available to you in the ocean. Where are you located? seems to me you have a very unorthidox mixture of critters to keep in a tank as you wish list. Remember the lion fish will eat whatever can fit in it's mouth, and their mouths open very wide!
Is the tank going in a home, business? Seems you have a very large space to use and a tank that large is going to require a lot of maintenance and money to setup and keep up.
