IMO, I think you should read, read, then read, some more on the this hobby. Find out about the tanks, setup, equipment, the up keep, the types of fish, corals, and inverts you'd like to keep and the requirements for keeping them. It will save you a lot of money, headache, and heartache in the end. Plus, it may save a few fish, corals, and inverts lives. But, like I said that's just MHO.
