The light-eyed fish (Procatopodidae) are a family of fish from the order of the toothfish (Cyprinodontiformes). They live widespread in Africa south of the Sahara and in the area of ​​the Nile.

features

Luminous eye fish are mostly bluish or greenish shiny colored fish. They are 2 to 15 cm ( Tanganyika light-eye fish ) long, are elongated and only more or less clearly flattened laterally in the rear third of the body. The name-giving feature is the light spot in the upper half of the eye, another is the cartilaginous mesethmoid (a skull bone).

Way of life

Luminous eye fish live in slowly flowing or standing, as well as in fast flowing small bodies of water, as well as in large lakes. They are predominantly schooling fish that live near the water surface and live on approach food. Young fish tend to live in protected areas, while adult fish are mostly seen in open water. Most luminous-eye fish spawn in fine-feathered plants where the eggs stick (adhesive spawners). The eggs are relatively large. The fry hatch after about 10 to 14 days.

species

The luminous eye fish include almost 80 species:

Systematics

The Procatopodinae were described by the American zoologist Henry Weed Fowler in 1916 . They were initially assigned as a subfamily to the egg-laying toothcarps . In a comprehensive revision of the toothfish, the American ichthyologist Lynne R. Parenti placed the Procatopodinae together with the subfamily Aplocheilichthyinae, which are also known in German as light-eye fish, in the family Poeciliidae. After further processing by Ghedotti the subfamily Aplocheilichthyinae included only the Nackenfleckkärpfling ( Aplocheilichthys spilauchen ). All other luminous eye fish were assigned to the Procatopodinae.

The group is, however, closer to the Mittelmeerkärpflingen ( Aphanius ) and the genus Valencia used as the livebearing toothcarps (Poeciliidae). The subfamily Procatopodinae was therefore raised to family status in February 2018 (now Procatopodidae). Aplocheilichthys spilauchen was also assigned to the Procatopodidae. The South American luminous-eye fish ( Fluviphylax ) became an independent family.
