Saltwater Aquarium Instant Ocean Starter Kit?

What sizes do they come in? The biggest i've seen was a 29 gal. So if that's the biggest i guess that's what i'll get. Now once i get it which won't be for a couple months, but i want to make it a reef tank and keep i guess 5 or maybe more small fish? This starter kit does come with the required lighting for a reef tank right? I know with a reef tank and a bio filter a lot of algae will form so i will be buying a protein skimmer, but what fish can i keep in a twentynine gallon reef tank? like clowns and what else...If instant ocean makes a 55 gallon i will be getting that so suggestions for that too please...thanks for all the help
