You don't need a skimmer on your tank. Just keep up with your weekly water changes and the live rock will take care of the rest. As far as fish suggestions go there are lots of small fish that would go nicely into the tank and it's going to be up to you what you like. Small gobies, percula, ocellaris or sebae clowns, firefish, yellowtail blue damsel, small fairy wrasses. All would work and are reef safe. A cleaner or peppermint shrimp would be nice to. You may need a nano size powerhead for in tank circulation, I'm not sure if the stock system provides enough. Of course you'll need food, frozen mysis and a good quality pellet food such as Ocean Nutrition. And you'll also need some patience to let the tank cycle for about a month before adding any fish.
