Scientific name

( Géry , 1960)

The yellow phantom tetra ( Hyphessobrycon roseus , syn .: Megalomphodus roseus ) is a freshwater fish from the family of the real tetra that comes from the waters of French Guyana (catchment area of ​​the middle and upper chestnuts and oyapock ) and Surinam ( Tapanahony ) .

features

The petite animals reach a length of only about 3 cm. In contrast to many other representatives of the genus Hyphessobrycon , its dorsal and anal fins are not drawn out like a flag. Its back is brown-olive, the sides pink, the belly yellowish-white. Behind the gill cover is a large, downwardly pointed black spot. The iris is black, the caudal fin stalk and the region above the anal fin are red-brown, the outer areas of the dorsal fin and the first rays of the anal fin are blue-white.

The yellow phantom tetra lacks the pronounced sexual dimorphism of the other phantom tetra species. The males are a bit slimmer than the higher back females. In addition, in contrast to the males, the females often have a yellow spot on the base of the anterior dorsal fin.

Way of life

In its area of ​​distribution, the yellow phantom tetra lives on the edge of streams and inlets of rivers with little flow. The bank areas are characterized by emersed bank vegetation reaching into the water , a lot of dead wood and a layer of leaves covering the bottom of the water.

Measured values ​​at the Tapanahony site at 25 ° C resulted in very soft (KH and GH <1 ° dH), acidic (pH 6.5) and low-salt water (conductivity <10 µS / cm).

Aquaristics

attitude

The yellow phantom tetra was first imported to Germany in 1984 (1978 to Holland). A group with no fewer than 12 specimens of the Yellow Phantom Tetra should be kept in a well-planted pool that still leaves enough space for swimming . A socialization is only recommended with other, smaller, non-predatory species. The pool length should be at least 60 cm, better 100 cm. Keeping them in medium-hard and slightly alkaline water is possible. Dry, fine live food and frozen food are accepted as feed.

Like most tetra species, the yellow phantom tetra is only a schooling fish in the event of danger or as a young animal . Otherwise he looks for an individual distance to his fellow species and shows an interesting social behavior with imposing behavior and ritualized mock fights .

Reproduction and breeding

The reproduction and breeding of the yellow phantom tetra hardly differs from that of the black phantom tetra . The previously proven upper limit of water hardness is 4 ° dGH and is thus lower than that of the black phantom tetra. Successful breeding has so far only been possible in peat-filtered water.
