Aphyosemion australe (Aphyosemion australe) – a freshwater fish of the order of the carp-shaped fish.


The Kap Lopez pennant lives in the streams of tropical West Africa , mainly in Cameroon, Gabon and Zaire.

Characteristics and disposition

They reach a length of 6 cm. Calm, gentle fish with an elongated, flattened dorsal body. Males can be recognized by their elongated fins and wonderful coloration.

There are several breeding forms, e.g. orange, golden, chocolate and albino. The fish live up to 3 years and are more long-lived than most oviparous carp. Considered ideal for aquarists who come into contact with carp for the first time. They are easy to reproduce, live quite a long time, decorative forms are relatively durable and easily acclimatize.

Some males may be aggressive towards each other.

Nutrition and feeding

Fish are more likely to eat small food, live or frozen, such as daphnia, but they can also be given good quality dry food.


For one pair or a harem, an aquarium of about 30 l and dimensions of at least 45x25x25 cm is sufficient. A tank with a dark substrate should be densely planted with plants, also floating, which will reduce the amount of light reaching the tank. Preferably soft to medium-hard water.

Pennants are good jumpers so a cover is essential. The filter in the aquarium should produce a gentle current of water. They are very peaceful and shy fish that will be chased away by the lighter or larger species. They can be kept in a social aquarium with small, gentle fish such as rapids , neon , razbora , cuirass , cichlids .


Breeding is relatively easy.

You will need a 10-15 liter spawning tank with a small sponge filter. The water should be soft and acidic with a pH of 6.0-6.5 (some growers manage to reproduce in water up to 8 ph). Water temperature 21-24 ° C. It is very advisable to filter the water through the peat . We shade the tank.

Breeders recommend separating females from males before spawning and feeding copiously with varied, live and frozen food. We put steam in the tank. If the water parameters are good and the parents are in good condition, spawning takes place. In nature, the roe is laid in the ground or in plant clusters in the aquarium, small-leaved plants such as moss, peat or artificial aquarium mops are used. The eggs can be left with their parents, but some of them will be eaten.

The female spawns about 10-20 pieces a day for about 2 weeks. Fish do not bear spawning (especially the female), so we keep a pair for the longest week. The roe can be incubated in a peat layer in e.g. margarine containers. It should be noted that the roe does not become moldy and any such moldy eggs should be removed.

Hatching takes about 10-20 days depending on the temperature. Roe and fry are very light sensitive. Small individuals are large enough that we can feed them, for example, with artemia. We give the food twice a day and change the water every 2-3 days.
