Distribution and habitat
The Schmucksalmler are native to the catchment area of the lower Amazon in Brazil. They live in forest streams and tributaries of large rivers with dense riparian vegetation and tree roots and branches protruding into the water
Maintenance
The aquarium should have a varied, partly dense planting, with shelters and hiding places (roots) and provide sufficient swimming space. Soft, slightly acidic water, a dark substrate covered with some foliage (e.g. sea almond leaves), shaded light (floating plants) and 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 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 very peaceful schooling fish can be kept very well with other peaceful, but also with lively fish as well as with shrimps in a community tank. They should be kept in a group of at least 5-10 fish.
Basically, only mutually compatible fish species with similar demands on water conditions and water temperature should be socialized
Sex dimorphism
Males have extended and more pointed dorsal fins, are more intensely colored, and are slightly smaller than females
Reproduction and breeding
They are free spawners. In soft, slightly acidic peat water they usually spawn between fine-feathered plants. The larvae hatch after about 24 hours and swim freely from the 5th day. The parents do not engage in brood care and should be separated from the fry after spawning, as they are spawn predators.
Juveniles must be fed several times a day with special rearing food (dust food). Breeding is hardly possible in community tanks, as the spawn is easy prey.
Important
Jewel tetras are colored bright red to almost translucent, depending on their origin
The foliage (sea almond tree, oak, etc.) enriches the water with humic substances, naturally lowers the pH and promotes the development of microorganisms when rotting, 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.
