Red phantom tetra
|( Géry , 1961)|
The hyphessobrycon sweglesi or Swegles-tetra ( Hyphessobrycon sweglesi , Syn. : Megalamphodus sweglesi ) is a freshwater fish from the order of Characins (Characiformes). It comes from the area of the Rio Muco and the upper Río Meta , two tributaries of the Orinoco located in Colombia . Red phantom tetra grow up to four centimeters long.
The red phantom tetra has a delicate pink body that becomes more reddish towards the back and slightly gold towards the belly. It has a very large, deep black, triangular to round shoulder spot.
Male and female specimens of the red phantom tetra can be clearly differentiated from one another ( sexual dimorphism ). The male shows a strong red color of the unpaired fins and pelvic fins especially in courtship and during fights. The dorsal fin (dorsal) is elongated like a flag and has a black border or spot at the upper end. The dorsal fin of the female is smaller than that of the male and has a large black spot, which is lined with white on the upper edge and orange on the lower edge.
Way of life
The red phantom tetra lives in its range in ponds and small rivers. These waters are mostly clear, very soft and acidic and have heavily weed bank zones, on the edge of which the red phantom tetra prefer to stay and in which they flee in case of danger.
Measurements at a location in a pond 80 km south-east of Puerto Gaitán near the Rio Muco showed a pH value of 5.5 at a water temperature of 28 ° C, a water hardness <1 ° dGH and ° dKH and an electrical conductivity <10 µS / cm .
The red phantom tetra was first imported to Germany in 1961. It is very sociable and should therefore be kept in groups of 12 or more. At the same time, the aquarium should offer enough space in order not to fall below the preferred individual distance, as especially male specimens claim small, temporary territories and defend them through commentary fights . The side length of the aquarium should be at least 60, better 100 cm.
The pool should be well planted and at the same time offer enough free swimming space. In particular, shaded areas of the transition zone are often used as a stand and promote well-being. The red phantom tetra makes no special demands on the food and can be fed with dry, fine live and frozen food.
Contrary to the very soft and acidic water parameters at the place of discovery, the red phantom tetra can also be cared for persistently in medium-hard and slightly alkaline water. Different information is given in the literature on the preferred water temperature. The 28 ° C measured several times at one of the sites speak for tropical values. While there are isolated literature examples that also indicate the range of 22-26 ° C that is usual for tropical freshwater fish, the frequently cited Hans A. Baensch and Rüdiger Riehl recommend 20-23 ° C in their aquarium atlas, as the most common mistake in the care of the Red phantom tetra is too high a water temperature.
Reproduction and breeding
The conditions for successful reproduction and breeding are comparable to those of the black phantom tetra . The proven upper limit of water hardness is 4 ° dGH, slightly lower than that of the black phantom tetra, and the red phantom tetra is also less productive. Hans A. Baensch and Rüdiger Riehl recommend a lower breeding temperature of 20–22 ° C.
