Distribution and habitat
The distribution area of the red fringed dwarf cichlids is the catchment area of the lower Rio Negro and the Rio Branco in Brazil. They live there in shallow, plant-rich small waters and in the shore zones of streams and rivers.
Maintenance
The aquarium should have a dense planting, with many hiding places (stones, roots, caves) and offer free swimming space. A dark substrate covered with some foliage (e.g. sea almond leaves) and slightly dim light (floating plants) 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 the wild they feed mainly on small crustaceans and insect larvae. 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 for cichlids (flakes, granules, pellets) as well as daphnia, artemia, mysis, 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
They should be kept in a harem, one male with several females. They are very territorial, so keeping multiple harems is only recommended in a larger and richly structured tank. With other calm fish they can be kept well, but consistently defend their territory
Basically, only compatible fish species with similar demands on water condition and water temperature should be socialized.
Sex dimorphism
The male is larger, more colorful and has much longer, pointed fins. The female is smaller and colored yellow in the spawning season.
Reproduction and breeding
They spawn in caves (cave breeders). The female performs the brood care, while the male defends the territory. After 3-5 days the fry hatch, which are then housed and guarded by the female in a bottom pit until they swim freely after 4-5 days.
Fry must be fed several times a day with special rearing food. Breeding is hardly possible in community tanks, where the fry are easy prey.
Important
The foliage (sea almond tree, oak, etc.) enriches the water with humic substances, naturally lowers the pH and is 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 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.
