Moenkhausia
Red Eye Moenkhausia (M. sanctaefilomenae )
Moenkhausia is a genus of the family of Real tetras ( Characidae ). The genus was erected in 1903 by Carl H. Eigenmann, who missed the genus names in honor of his friend WJ Moenkhaus. Moenkhausia species are widely distributed in South America. Especially the Brillantsalmler and the red-eye Moenkhausia are often held freshwater ornamental fish.
Features
The genus combines a variety of very different tetras with relatively deep-bodied and with elongated, fusiform shape. Moenkhausia species are 3.4 cm to 10 cm long. The lateral line is complete ( except Moenkhausia sanctaefilomenae ) and is straight or only very slightly bent downward. The caudal fin base is scaly like Hemigrammus, the scales on the tail fin base are smaller than the scales on the rest of the body. An adipose fin is present. The maxilla is usually staffed with three teeth that are directly behind the Prämaxillar - maxilla connection. Some species are also toothless. In the males of some species, such as when Brillantsalmler are dorsal and anal fin enlarged.
Way of life
Moenkhausia species are schooling fish mean water regions. Some types are to be temporarily revier forming. They operate no brood care, but give their spawning than free spawners in Fine-leaved aquatic plants or just below the water surface.
