Distribution and habitat

The Orange Lemon Tetra is a color morph native to the Rio Tapajos watershed. They live in slow flowing tributaries with dense underwater vegetation, in weedy streams as well as in floodplains.

Maintenance

The aquarium should have a varied, partly dense planting, with shelters and hiding places (roots) and provide sufficient swimming space. A dark substrate covered with some foliage (e.g. sea almond tree, oak), shaded light (floating plants) and slightly acidic water with a weak current is ideal.

No ammonia, ammonium and nitrite should be detectable, 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 nature they feed mainly on small insects, insect larvae and plankton. The food supply consists of live, frozen and dry food. For a balanced diet, feed once a day with a high-quality, protein-rich dry food (flakes, granules, pellets) as well as cyclops, moina, daphnia, artemia, mosquito larvae, etc. (live or frozen)

It is recommended to feed small portions several times a day. Only feed as much as will be eaten within a few minutes. A regular and varied diet promotes health and increases resistance.

Behaviour and compatibility

These swim-joyful swarm fish can be maintained very well with other small and peaceful fish as well as with shrimps in a society tank. They should be kept in a group of at least 5-10 fish.

Basically, only mutually compatible fish species with similar requirements for water conditions and water temperature may be socialized

Sex dimorphism

The sexes are difficult to distinguish. The anal fin of the male is more clearly fringed with black

Reproduction and breeding

They are free spawners. In soft, slightly acidic peat water they spawn mostly between fine-feathered plants up to 300 eggs. The larvae hatch after 24-36 hours and swim freely after 3-4 days. The parents do not engage in brood care and should be separated from the fry after spawning, as they are spawn predators.

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

Important

The foliage (sea almond tree, oak, etc.) enriches the water with humic substances, naturally lowers the pH and, when rotting, promotes the development of microorganisms, which are a valuable secondary food source.

The well-being of the fish should be monitored regularly. Temperature should be checked daily, pH, hardness and nitrate levels at least every 14 days. Regular partial water changes are recommended, even when contaminant levels have 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.
