seeking suggestions for a new saltwater aquarium

[swiftlynx]

hey so i'm upgrading to a 55 gal for my freshwater setup, which means my 20 gal is now free for a saltwater tank i've never done saltwater before, so i'm starting from scratch what are the essentials i need to get, and what are some cool ideas for a small tank like this??

You thinking just fish or wanna try some corals and stuff too?

prob just fish for now, still getting used to the idea of a saltwater tank

if you're just sticking with fish, a couple gobies or blennies could work out or maybe a pair of clowns with a shrimp or two thrown in, and then you could also add some smaller stuff like hermit crabs, starfish, snails, or even an urchin

ok so i've narrowed down the fish i want for my saltwater tank - either a pair of Sixline Wrasse or those black and white clownfish, can't remember the exact name but they're really cool looking. now that i've got my fish in mind, i'm stuck on the rest - what kind of media should i use, live rock? what about filters? and what's the deal with skimmers? i read somewhere that for a nano tank like mine, a skimmer isn't necessary. would love some input on this.
