Jewelry fin Fiederbartwels ( Synodontis eupterus )
The jewelry fin, high fin or fins spring - Fiederbartwels ( Synodontis eupterus ) is a member of the comprehensive over 130 species genus Synodontis, which belongs to the family of Catfishes ( Mochokinae ) the Mochokidae family. The species was described in 1901 as Synodontis eupterus scientifically. The species name is from the Greek, derived from eu, for 'beautiful' and pteron for, Fin '. Although the first introduction of this catfish for aquaristic purposes can not say exactly, but around 1990 she appeared in the hobby literature.
Features
The distinguishing feature of this catfish is, how can the name suggests, the dorsal fin, the anterior rays are greatly extended in adult animals. Young animals, however, feature on caudal peduncle, before and after the adipose fin, a narrow, slightly wavy, almost white vertical line that is surrounded on both sides by a dark border. At this age, the fins are more or less banded. With age, the white line disappears and the edge and the tapes dissolve rapidly into individual points. Finally, the whole body is covered with small, blackish points, in not too closely spaced. The ground color is brownish olive color.
Occurrence
The range extends from the middle Nile ( Lake No is the type locality ) on the Chad basin to the Niger and Volta system.
Size
Depending on the source is mentioned 15 to 23 centimeters in total length.
Behavior and reproductive biology
A peculiarity of this catfish is that they occasionally swim on their backs. This may be because they are available under roots, with the belly up. If you then, well covered, flit from one root to another, it may not be worthwhile extra- turn to overcome the small distances. The back Floating Congo catfish used this particular swimming position even in the "continuous operation ". As well as other individual Synodontis species stand out in this way, ie, the whole family in English as " upside-down Catfishes ". S. eupterus regarded as peaceful foster child in the aquarium. However, this catfish should not be associated with fish that tug at fins, since the extended fin rays of the dorsal fin animate such species.
The Reproduction of jewelry fin Fiederbartwelses is not precisely known, but it is believed that they are free spawners. Although S. eupterus has not yet been bred pure in captivity, hybrids are offered by this kind in the ornamental fish trade. This can be achieved especially in Eastern Europe by hormone injections ( pituitary extracts ).
