Does a 10G Aquarium Need Skimmer? Powerhead?

You don't need a skimmer if you do water changes every week. I would use a power head to keep algae from growing on rock and to circulate nutrients to corals. Putting anemones in a new set up is usually not recommended, most will die. Let the tank run for at least 6 months. Clowns do not need an anemone in the tank and mine have survived 4 years without one just fine so you can get the clowns after the tank has cycled but you might want to hold off on the anemone.
