Fish an aquarian Royal tetra - Nematobrycon palmeri

Palmeri or the Royal tetra - Nematobrycon palmeri Eigenmann, 1911 Characida

Though this magnificent fish was described in 1911, in the European aquariums she appeared as the novelty only in 1959 of Nematobrycon palmeri is found in Colombia in water system of the river San Juan. 5,5 cm reach. Differs from other tetrovidny fishes in the fact that it has no fatty fin (pinna adiposa). It is easy for Paule to distinguish - the average beam of a tail fin of males is extended. Females slightly more small than males, their paunch are more stout, coloring is not so expressive.

Successful cultivation depends on successful selection of males as the weight of evidence suggests that not all males are productive. On spawning of fishes put on couples in spacious aquariums (pribl. 10 liters). Before spawning of females otsazhivat for two weeks. Experience shows that water from an aquarium of producers to which it is possible to add peat extract is suitable for normal development of berries. Optimum temperature fluctuates from 24 to 26 °ts. Other parameters: rn 7.0-7.5, dGH 10 °, dKH less than 2 °. In too acidic and soft water the incubation of berries proceeds without complications, however whitebaits often have then dropsy. Fishes willingly spawn, especially if before spawning they were isolated from each other, but their fertility is low. Larvae are pecked out in 24 hours, and for the fifth day whitebaits begin to float. Thresh cultivation comes easy, feed her with an artemiya, later - the cut trubochnik.

N. palmeri well looks in big group. Vessels have to be spacious with scattered lighting and a dark bottom. In polyculture of N. Palmeri best of all feels in the company of small tetrovidny fishes. A favourite forage - larvae of mosquitoes or qualitative oat food. Except a trubochnik they can be fed up front sights (river of Drosophila). Received the name "royal tetra", probably, because in group of fishes the strongest male who resolutely drives away other males bosses, than makes impression of the master of group. At the same time, the same behavior can be observed also at other species of fish. Very similar look is N. lacortei which is found in aquariums is rare, and only recently found, smaller type of Inpaichthys kerr.
