Sunface damsels(talbot) are considered one of the better damsels for a reef tank. Some info on these wonderful fish
The Talbot's Damsel Chrysiptera talboti is a very beautiful and rewarding fish to keep. It's small in size reaching only 2 1/3 inches (6 cm) long, an active swimmer and a great eater. It is also very hardy, often available and moderate in price, making it a great fish for a beginner or any other saltwater enthusiast.
These pretty fish have such a distinct look to them that they are very hard to confuse with any other damselfish. A bright yellow face and forehead contrast with body colors that can range from pink or pinkish purple, to gray or darker, accented with yellow anal fins. These are also one of those interesting fish with an ocellaris, or "eye spot" located at the base of its dorsal fin. This special black marking helps confuse predators, offering the fish protection from frontal attacks.
This little treasure is one of the true pacifists of its genus with a wonderful, easygoing disposition. It has the mellowest temperament you can get from a damselfish with behaviors much like its even tempered clownfish relatives, the Percula, Ocellaris and Skunk Clowns. In fact the Talbot’s Demoiselle gets along well with many peaceful companions. But unfortunately it is the one that tends to get picked on by other fish, making proper tank mates essential so it doesn't get stressed out.
These colorful little fish are very easy to keep. They are are not picky eaters and will happily accept just about any foods you offer. Rock work or coral in and around all areas of the tank can provide lots of hiding places, and that will keep them content. They do not need any special lighting or water movement, but they do prefer to hang out at the bottom of the tank, They will burrow under under rocks, a large shell, or a coral, and then retreat into their little home at night, so a sandy bottom is preferred.
The Talbot’s Damsel are great for any peaceful community tank. They need a minimum tank size of 20 gallons for one, or to keep a male/female pair. Be very careful when adding other fish if you have a mated pair, however, since all damsels and clownfish claim territories which they will then strongly defend. They get along with peaceful fish in larger tanks that are at least 40 gallons. Of course, if you are going to have larger fish like a large surgeonfish/tang, the tank size should fit the needs of the largest fish. These damsels also make a great addition to a reef tank because they will not bother any corals or invertebrates.
