Starting a tank

I am getting help from an experienced saltwater tank owner and i would like to know what should i get for a 20 gallon hexagonal tank?

 

Fish wise, you can keep about 3 small fish.

A pair of clowns, or just one. Fire fish, Royal gramma, Cardinals, smaller gobies.

When I window shop for fish I like to look at liveaquarias site.

Saltwater Fish: Marine Aquarium Fish for Saltwater Aquariums

 

You can really get most everything that will stay under about 3.5" anything bigger will get uncomfortable.

Things i would suggest that will stay small.

Pair of clowns(Ocelleries Clowns, Perc Clowns,Skunk Clowns,Tamatos and maroons get to big)
Wrasses, most of these stay pretty small..A few types can get a lil big.

Most gobies you should be fine with, but no sandsifting gobies, they need a bigger tank to survive in.

Cardinal types should be fine.

And another thing you should look into are some cool inverts, like urchins,starfish,cool crabs and stuff..There are alot out there im sure you can find something like a shrimp thats cool once you run outa room for fish.
