Alestopetersius caudalis

12. March 2021

The Yellow Congo Tetra (Alestopetersius caudalis) originates, as the name suggests, from the Congo. However, it is almost never traded as wild catch, because it can be bred very well. With a final length of about 6 cm it belongs to the smaller species of the Congo tetra relationship. In the course of its aquaristic career it has already changed the genus name several times and one finds it in the literature also as Hemigrammopetersius caudalis or Phenacogrammus caudalis.

Depending on the incidence of light, the animal looks different. In light from above it is yellowish-transparent, in light obliquely from above the back glows blue and in light from the side the body sparkles as if it is set with diamonds.

Alestopetersius caudalis is completely peaceful, but somewhat shy, which is why it should be kept in as large a group of conspecifics as possible in a densely planted aquarium that also leaves enough swimming space, with light that is not too bright. Each drinking water is suitable for the care. However, the animals show the most beautiful fin development in soft, slightly acidic water (pH around 6). The temperature should be between 22 and 28°C. All food of animal origin is eaten, no matter if dry, frozen or live food. A special joy for the animals is feeding them small fruit flies (Drosophila), a trick breeders use to achieve the most abundant spawning of females.
