Yes, before we scare this new reefer into next week, let's also mention the cheapest way into this hobby to be able to keep very many things, and that is the Aquapod, Solana, etc, ---the all-in-ones. They have miniaturized but functional equipment, let you learn the ropes until you're sure whether this is for you, you use it until you get too ambitious---and then you sell it on to the next person. A used Aquapod could get you into the hobby for not very much cash at all: new, they're around 300.00. Check out Foster-smith etc, on the all-in-ones and then check out the Used Equipment forum and you may feel a lot less wallet-shock!
There are quite a few marine fish and inverts that do nicely in a pod: the smallest clowns, gobies, blennies, all colorful and personable fish: these are good systems, and you don't have to be a master chemist or plumber to get set up: they work pretty well out of the box, some sand, live rock, and a month's patience and you're up and running.
