Chrysiptera hemicyanea, known commonly as the azure damselfish, azure demoiselle, half-blue demoiselle, and yellow-dipped damsel, is a species of damselfish.
The generic name, Chrysiptera, is a compound of the Greek words chrysos, meaning "golden" and pteron meaning "fin" or "wing", while the specific name, hemicyanea, means "half blue" referring to the blue head and upper body. [2]
It is native to the eastern Indian Ocean and western Pacific. [3] It has also recently been filmed in the Mediterranean Sea off Malta. [4]
Being a reef species, these fish are found in greatest population in whats known as the Coral triangle, which is one of the largest concentrations of coral reefs in the world, located form the Solomon Islands to Indonesia, Bali and the Philippines. [3]
Typically found in waters 1 to 38 m (3 to 125 ft) deep and are non migratory. [3]
This tropical marine fish reaches 7 centimetres (2.8 in) in length. It is mostly bright blue in color, with a bright yellow bottom. [3] Different species in this genus have varied amounts of gold coloring.
As a tropical species, these species are found in coral reefs habitats near the equator. They inhabit lagoons or near shore reefs and are typically found in rock structures or around branching corals like Acropora corals. [3] This species is a reef dependent species that needs corals or other structures for protection from predators. Primary eat plankton and small invertebrates.
The reproduction of Chrysiptera hemicyanea is not well studied. Reproduction in the genus Chrysiptera involves mating pairs, followed by a benthic egg-laying life cycle, where eggs are adhered to a substrate and a male stays around to guard and aerate the eggs. In addition this genus has a shorter larval stage when compared to other damselfish and because of these two things have issues distributing. [5] Population has the ability to double in 15 months. [3]
The primary way to protect this species is to maintain their primary habitat which is coral reefs. In current times coral reefs are beginning to disappear in most areas due to coral bleaching. [6] Coral bleaching occurs when warmer average temperatures cause corals to begin to overheat and die, turning them white. Global warming is thought of as the primary cause reef destruction, and will only worsen in the coming decades. [6] It is projected that by the middle of the century there will be severe damage to global coral reefs. As coral reefs die out it may become necessary to supplement structure like artificial reefs or any type of structure that fish has hide in.
This fish is a popular species in the home aquarium along with some closely related species like Chrysiptera talboti and C. rollandi . In captivity they are quite hardy and easy to take care of. They can tolerate some minor changes in water chemistry and are recommended for beginners in the saltwater aquarium trade. This species will eat just about anything including fish flakes and frozen brine shrimp. [5]
Even though they are considered a schooling fish (especially stay around the SPS corals), they are quite aggressive and territorial. Fish that invade the area are harassed, sometimes to death. The best way to avoid this is to place fish in a large enough tank with plenty of structure like coral or live rock. [5]
Recently this species has been successfully bred in captivity to try and increase the supply to the aquarium trade and decrease the environmental impact.
Pomacentridae is a family of ray-finned fish, comprising the damselfishes and clownfishes. This family were formerly placed in the order Perciformes but are now regarded as being incertae sedis in the subseries Ovalentaria in the clade Percomorpha. They are primarily marine, while a few species inhabit freshwater and brackish environments. They are noted for their hardy constitutions and territoriality. Many are brightly colored, so they are popular in aquaria.
The yellow tang, also known as the lemon sailfin, yellow sailfin tang or somber surgeonfish, is a species of marine ray-finned fish belonging to the family Acanthuridae which includes the surgeonfishes, unicornfishes and tangs. It is one of the most popular marine aquarium fish. It is bright yellow in color, and it lives in reefs. The yellow tang spawn around a full moon. The yellow tang eats algae. The yellow tang has a white barb, located just before the tail fin, to protect itself.
Paracanthurus hepatus is a species of Indo-Pacific surgeonfish. A popular fish in marine aquaria, it is the only member of the genus Paracanthurus. A number of common names are attributed to the species, including regal tang, palette surgeonfish, blue tang, royal blue tang, hippo tang, blue hippo tang, flagtail surgeonfish, Pacific regal blue tang, and blue surgeonfish.

Abudefduf troschelii, the Pacific sergeant major or Panama sergeant major, is a species of damselfish belonging to the family Pomacentridae that can be identified by the pronounced black stripes on the lateral sides of the fish. Its specific name honors the zoologist Franz Hermann Troschel (1810-1882). It is native to the neritic pelagic zone of the shallow water coral reefs in the Eastern Pacific Ocean and they are an omnivorous species feeding on plankton and algae attached to their coral habitat. Abudefduf troschelii is a sister-species of A. saxatilis but have diverged from each other since the uplift of the isthmus of Panama, separated by the rise of the Panama land bridge 3.1 to 3.5 million years ago. Males, like in many other marine species, take care of and defend newborn A. troschelii after they have been hatched by eggs from the female. There are currently no major threats to the species and there is no indication of a current decline in its population size. The IUCN Red List lists this damselfish as being of “least concern”.
