Fish that I would consider include the Pygmy Angels, such as the KeyHole or the Coral Beauty, smaller Gobies, such as an Engineer Goby or Twinspot, the Firefish or Dartfish Goby/Family, a favorite, some Clownfish, and if you are so inclined, maybe 2-3 Damsels by themselves. I'm not saying get one of all, I'm just saying that these are good, smaller fish. Especially the Clowns, who are practically genetically geared for tanks. Even in the Ocean they are restrict themselves to a very small area surrounding the host anemone, so they are perfect for the captive aquarium.
Also, a couple of Fish Families to avoid. Avoid any of the Groupers, most Eels, most Scorpionfish, all Tangs, all Butterflies, all Large Angels, any Sharks obviously, and most importantly, don't...look...into...the...paisly...light... Meaning, don't go out and get a Mandarin, as even a few months on this board should have taught you.
I've left off a lot of canidates for smaller aquariums, and that's mainly because I've forgotten them, but some of them I left off because I don't believe they are suited for a smaller Reef community. I've also left off a number of families that should be kept out of your tank, and hopefully some other members will chime in with ones to avoid. Good Luck and Welcome to the Board!
