Fish vertebrate animal that lives in water and (typically) has gills

Fish are gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered paraphyletic by excluding the tetrapods. Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology, unless it is used in the cladistic sense, including tetrapods. The traditional term pisces is considered a typological, but not a phylogenetic classification.

Aplocheilidae family of fishes

Aplocheilidae is a family of fish in the order Cyprinodontiformes found in Africa, Asia and the Americas. This family-group name is well-established, making its use as a single aplocheiloid family more stable along time, besides avoiding the impact of a new name at the family rank for a popular aquarium fish group. Following this proposal, Aplocheilidae includes three subfamilies: Aplocheilinae for the species from Asia, Madagascar and the Seychelles; Cynolebiinae for the species from the Americas; and Nothobranchiinae for the species from the African mainland.

Endemism Ecological state of being unique to a defined geographic location or habitat

Endemism is the ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. The extreme opposite of endemism is cosmopolitan distribution. An alternative term for a species that is endemic is precinctive, which applies to species that are restricted to a defined geographical area.

Pachypanchax playfairii, the golden panchax, is a species of Aplocheilid killifish, the only species of freshwater fish endemic to the Seychelles, a group of islands in the Indian Ocean directly east of Tanzania, and the only member of its genus found outside of Madagascar. An egg scatterer, the golden panchax breeds amongst floating water plants. This species is unusual in that the scales of the male become lifted during the breeding season, giving the skin a rough appearance. Unlike the true annual killifish, they live as long as similar fishes, a few years, 3 years is not uncommon 5 is unknown.
