Moray eels, or Muraenidae, are a family of eels whose members are found worldwide. There are approximately 200 species in 15 genera which are almost exclusively marine, but several species are regularly seen in brackish water, and a few are found in fresh water.
Chromis is a genus of fish in the family Pomacentridae. While the term damselfish describes a group of marine fish including more than one genus, most damselfish are in the genus Chromis. These fish are popular aquarium pets due to their small size, tolerance for poor water quality, and bright colors.
Dascyllus is a genus of fish in the family Pomacentridae. They are usually commensals with corals.
Pseudojuloides is a genus of wrasses native to the Indian and Pacific Oceans.
Fusigobius is a genus of coral reef inhabiting gobies found throughout the Indian and western Pacific Oceans.
Plectranthias is a genus of fish in the family Serranidae found in the Atlantic, Indian and Pacific Ocean.
Valenciennea is a genus of small, bottom-dwelling fish in the family Gobiidae. They are found over sandy bottoms, often at coral reefs in the Indo-Pacific. The members of the genus tend to rest directly on the substrate for extended periods of time. While this is a common behavior for members of the family, this genus also float motionless directly above the substrate, which is why they are sometimes called glider gobies. Their resting behavior has resulted in the vernacular name "sleeper gobies", which invites confusion with the related family Eleotridae. The members of this genus are known to be carnivorous sand-sifters; to eat, they simply engulf entire mouthfuls of sand which they expel through their gills. Specialized structures in their gills filter small crustaceans and worms as the sand is expelled. It is this specific trait that makes some members of the genus attractive to the marine aquarist, and they are often introduced into a marine aquarium for sand-sifting. Some of the species are known to be monogamous. The genus was named after notable French zoologist Achille Valenciennes. These fish are difficult to keep in a tank. Tanks with plenty of live sand and live rock are recommended. Offer foods such as sinking shrimp pellets. Fish may die even if eating properly.
