Distribution and habitat

The distribution range of the Small Freshwater Needles extends from Senegal and Guinea through Nigeria, Cameroon and Gabon to Angola. There they live in the slow-flowing lower reaches of rivers and estuaries, where they usually stay near the shore among roots and dense underwater vegetation.

Maintenance

The aquarium should have a loose background and edge planting with tall plants (Vallisneria, etc.) and some roots (hiding places) and provide sufficient swimming space. A fine-grained substrate covered with some foliage (e.g. sea almond leaves) and medium to hard water is ideal

No ammonia, ammonium or nitrite should be detectable in the water, and the nitrate value should not exceed 100 mg/l. To ensure the water quality and oxygen content, a filter and heater adapted to the aquarium size is required, as well as lighting for the species-appropriate day-night rhythm of the animals.

Diet

In the wild they feed mainly on insect larvae and small crustaceans. The food supply consists of small live food, such as daphnia, mysis, artemia and black mosquito larvae, which is sometimes accepted in frozen form after habituation. Dry food (granules, pellets, flakes) is not accepted

They are very slow eaters and should be fed small portions several times a day. A regular and varied diet promotes health and increases resistance.

Behaviour and compatibility

It is recommended to keep them in a species tank. They are very peaceful and sociable fish that should be kept in pairs or better in a group. Keeping them in a group is only recommended in a larger and richly structured tank. Socialization with calm, peaceful fish that are not food competitors is possible

Basically, only compatible fish species with similar demands on water quality and water temperature should be socialized.

Sex dimorphism

The slightly larger males have a conspicuous furrow (breeding organ) on the abdomen, which becomes a gross pocket (skin sac) during the spawning season.

Reproduction and breeding

After courtship, the female transfers the eggs into the male's brood organ. The eggs are glued and held with a special tissue (skin sac). After 2-3 weeks the larvae hatch, they are released from the skin sac and the brood care ends.

Fry must be fed several times a day with special rearing food (infusoria, Artemia nauplii). In community tanks breeding is hardly possible, because the young fish are easy prey.

Important

They can be maintained in fresh or brackish water, although 1-2 teaspoons of sea salt per 10 liters should also be added to the fresh water.

These slow feeders can only take very small food, which they suck with their thin mouth tube (suction feeding). It is recommended to turn off the filter during feeding

The well-being of the fish should be checked regularly. The temperature should be checked daily, the pH, hardness and nitrate value at least every 14 days. Regular partial water changes are recommended, even if the contaminant level has not yet reached the upper limit. Sudden changes in water quality should be avoided. Newly introduced fish must be accustomed slowly to the water in the aquarium.
