Distribution and habitat
The distribution area of the red dwarf fighting fish is the area around Anjungan in the west of Borneo (Kalimantan Barat, Indonesia). They live there in shady small forest streams, pools and swamps of the rainforest.
Maintenance
The aquarium should have dense planting with many hiding places (stones, roots). A dark substrate with peat and oak and sea almond leaves and subdued light (floating plant cover) is ideal. They only need a shallow water depth, 25 cm is sufficient.
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
They prefer live food, accordingly the food offer consists of cyclops, daphnia, artemia, mysis, and mosquito larvae, which is accepted without problems also in frozen form, supplemented with commercially available, frozen special food mixtures. High-quality dry food (flakes, granules) is also well accepted.
Regular and varied feeding promotes health and prevents deficiency symptoms. Only feed as much as is eaten immediately (in a maximum of 10 minutes).
Behaviour and compatibility
They should be kept in a harem, one male with several females. Males have a pronounced territorial behavior among themselves and defend their territory consistently. Keeping several harems is only possible in a large, richly structured tank. They can be kept in a community tank with not too small fish and many hiding places, but better in a species tank
Basically, only mutually compatible fish species with similar demands on water quality and water temperature may be socialized.
Sex dimorphism
The sexes are difficult to distinguish. Males have longer extended fins, sexually mature females are slightly rounder.
Reproduction and breeding
They belong to the foam nest building fighting fish. The foam nest is built by the male, which also takes care of the brood. The eggs, which are ejected during the numerous matings (entwinements), rise to the water surface, are collected by the male and introduced into the nest. The larvae hatch after about 24 hours and swim freely after 2-6 days.
The fry must be fed several times a day with special rearing food (dust food, Artemia nauplii). In a community tank breeding is hardly possible, because the spawn is easy prey.
Important
They have an additional respiratory organ, the so-called labyrinth (suprabranchial organ) with which they breathe atmospheric air and can suffocate if this is not possible. The air temperature in the breathing area must not be lower than the water temperature! During the dry periods they can survive in small varnishes or in the damp foliage until the next rainy season
Other fish of similar shape and coloration are usually perceived as enemies.
The well-being of the fish should be monitored regularly. Temperature should be checked daily, pH, hardness and nitrate levels at least fortnightly. 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.
