The Powder Blue Tang - Acanthurus leucosternon - is relatively tough to keep for many reef keepers. This one came with my 280g tank, and was very thin at that time. I fed Nori every day, and he was always second in line to start eating the dried seaweed clipped to the glass. Later, he began nipping at the green star polyps and the Toadstool Leather. By increasing the food offerings, this declined somewhat. The Powder Blue became much thicker, and very healthy. Every night it was excited to get more meaty foods during the evening feeding.
The Lightning Maroon Clownfish is a gorgeous and rare fish, at this time, hailing from Papua New Guinea. Matthew Pedersen has been keeping one since 2010, and has a blog about the ongoing breeding process. Feel free to read about the offspring he coaxed out of this fish, and how they are slowly developing their own interesting patterns: http://www.lightning-maroon-clownfish.com
The Gem Tang - Zebrasoma gemmatum - is a stunning acquisition if you have the bank account to fund it. Pricing is so high that your best bet is to visit a public aquarium to see one in person. Same family as the Yellow Tang, this fish should be easy to care for in an appropriately sized tank.

The Pajama Cardinalfish is named because of the polka dotted tail section. When small, these fish are known to shoal together and add some unusual dynamic to the tank. While it only takes a male and a female cardinal to produce fry, multiple females will be happy with a single male companion. Cardinalfish are mouth brooders, meaning that the male will carry the fry in his mouth for about two weeks until they are ready to release, all that while he will forego any meals. His jaw area will be more pronounced, compared to the female counterparts.
One of the least expensive fish you'll add to your tank will be the blue & green Chromis fish. They are in the damsel family, and in a large group will shoal together all day long. Their silvery bodies nearly glow under reef aquarium lighting, and their activity will make your reef come alive. Chromis will eat most any food added to the tank. They prefer to tuck into various corals for protection at night, and their favorite colony appears to be the Birdsnest coral.
This delightful purple fish is one of many that are tank-raised by ORA in Florida. Pseudochromis fridimani can be purchased from your local fish store if they offer ORA fish, and if they don't, ask your LFS to order them in for you. I have had three of these in my reef since 2011, and they don't fight at all. Each has their own territory, but they aren't distantly spaced. While feeding, they are out and near each other as they wait for food to flow into their proximity.
The Amphiprion percula is my favorite fish, and this particular species is bred to create what are called Onyx Percs. During a trip to Oklahoma, I picked up a beautiful couple of Onyx percs (A. percula). Sadly, due to fish disease that entered my system (a sad reminder that quarantine is the only safe way to assure new fish don't harm those I already keep), these little fish didn't make it. Maybe I'll try again some day.
The Sebae anemone (Heteractis malu) is a lovely addition to a reef tank, but be aware it may eat some fish out of your system. My anthias disappeared, and I never found any bodies. The anemone got larger and larger though, and I never feed it directly. Correlation? hehe The Sebae anemone prefers to bury its foot through the sandbed and attach to the bottom panel of the aquarium rather than latch onto rockwork.
This image was swiped from Frag Junky (with their permission of course) to showcase the beauty of Maxi Mini carpet anemones. These are very sticky anemones that will catch fish that venture too close. Now that you know that, figure out how to set up a tank that will allow you to enjoy these gems.

Some comments by Michael: "The Gigantic Sea Anemone - Stichodactyla gigantea - loves warmer water (84 - 86F), and will move often if not feed. I feed mine 5 silversides a week. Intense lighting is a must (250w HQI 20,000K AB Metal Halide is what I use now), and weekly water changes. I believe clownfish are the key to keeping this anemone, because they seem to clean it daily and even bring it food. When hungry, the anemone contracts its tentacles and vibrates. Good varied flow seems to be ideal, but not directly on the anemone.
