The rosy barb ( pethia conchonius , Syn. : Puntius conchonius ) is from Asia originating freshwater fish . The fish, first introduced to Europe in 1903, has found widespread use among ornamental fish keepers because of its attractive appearance and the uncomplicated demands on the keeping conditions. There is a cultivated form with elongated fins that lives exclusively in captivity.
distribution and habitat
The barbel lives in ponds, ponds and rivers in Afghanistan , Pakistan , India , Nepal and Bangladesh with temperatures between 18 and 22 degrees Celsius. It prefers habitats with soft and weakly acidic water, but tolerates a pH value between six and eight and a water hardness between five and 19 degrees of German hardness .
Appearance
In its waters of origin, the magnificent barbel reaches a total length of 15 centimeters, but animals kept in aquariums remain much smaller with a maximum of eight centimeters. The body is typical of the species. The back is colored shiny olive green, the sides and belly are of a silvery red that turns into an intense ink red at spawning time. There is a distinct black spot on the caudal peduncle, roughly above the end of the anal fin . Male barbs have pink fins, with the tip of the dorsal fin being black. The fins of the female animals are colorless and their dorsal fins show only a touch of black. Males stay slimmer than their female counterparts. A clear sexual dimorphism is only seen in adult animals.
- Dorsal 3 / 7-8
- Anal 2 / 5–6
- Ventral 8-9
The barbel has 24 to 28 scales in a central longitudinal row (mLR).
Way of life
The peaceful schooling fish feeds on worms, crustaceans, insects and plants. The very productive pairing takes place after an intensive lovemaking associated with several false pairings. The larvae hatch after about 30 hours from a few hundred eggs attached to aquatic plants.
Systematics
The magnificent barbel was the eponymous species of the Puntius conchonius species group comprising more than 20 species , a group of closely related Puntius species, to which, in addition to the magnificent barbel, the bandula barbel ( P. bandula ), the Ceylon barbel ( P. cumingii ), P. didi , P. erythromycter , the spot bar ( P. Gelius ), P. macrogramma , P. manipurensis , P. meingangbii , P. nankyweensis , P. narayani , P. nigripinnis , the magenta head bar ( P. nigrofasciatus ), the Odessa barb ( P. padamya ), the dwarf bar ( P. phutunio ), P. punctatus , P. setnai , P. shalynius , the sunspots bar ( P. stoliczkanus ), P. thelys , P. tiantian , the two-point bar ( P. ticto ) and P. yuensis include . The species group was raised to the genus rank in 2012 under the name Pethia . The type species was not the magnificent barbel, but the purple-headed barbel.
