Pseudomugilidae
Tailed Blue Eye ( Pseudomugil furcatus )
The blue eyes ( Pseudomugilidae ) are a family of ears Fishy. This approximately five centimeters small permanent freshwater or brackish water fish are found only on the island of New Guinea (Papua New Guinea, West Papua ), the Aru Islands and Australia. Some species are kept as freshwater fish.
Features
Blue eyes have a slender, laterally strongly compressed body with large second dorsal and anal fin, the male part of large and tiltable dorsal fin. The pectoral fins are partially high, the peaks often reach over the body. The body is often transparent or slightly colored, the fins are often colored. The relatively large eyes are bright blue almost all species. Some species can reach up to 8 inches long (males). The less impressive females stay smaller.
Way of life
The natural habitats of the blue eyes are clear or teefarbene waters, with a few species also brackish mangrove forests. Blue eyes feed on mosquito larvae and other insects from the water surface.
Blue eyes are spawning period, females will often place over a longer period of time daily some eggs. The up to 2 mm eggs have custody threads which they use to attach themselves to the substrate or to plants. The larvae hatch in about two to three weeks.
System
The Pseudomugilidae were asked earlier than subfamily in the family of rainbow fishes ( Melanotaeniidae ). However, they differ from them in another building in the skull bones, which Saeed, Ivantsoff & Allen led 1989 's family of blue eyes ( Pseudomugilidae ) set up. Since 2004 they belong together with the Bedotiidae, Telmatherinidae and Cichlidae in the subordination Rainbow Fish Related ( Melanotaenioidei ). In addition to the listed scientifically described species, some species are still undescribed.

The Pacific Blue eye or butterfly blue eye ( Pseudomugil signifer ) is split into its occurrence due to a biogeographical boundary in at least two different subspecies.
