  • Scientific name: Betta persephone
  • Synonyms: -
  • Common name: Black dwarf betta
  • Group: Labyrinth fishes
  • Habitat:Asia; Southwestern Peninsular Malaysia
  • Size: 2-3 cm
  • Biotope: Inhabits around the towns of Ayer Hitam and Muar and Kluang in blackwater streams and in peat swamps with very soft and acidic water, usually among leaves and leaf litter. The fish was placed on the IUCN Red List of threatened species based on threats to its ancient peat forest habitat from logging.
  • Social behavior: Aggressive betta, not recommended for a community aquarium. Best kept in pairs in a species tank.
  • Diet: Omnivorous; in nature they eat small insects and zooplankton, in aquarium they accept live and frozen foods and even quality flake foods. A varied diet of live foods such as Artemia or bloodworm will help the fish to develop their best color. Take care not to overfeed them.
  • Breeding: Hard
  • Tank: Minimum 40 litres
  • Population: 1 pair for 40 litres
  • Decoration: Use well-planted tanks with hiding places made of roots, but most breeders use bare-bottomed tanks. The addition of dried oak leaves or peat extract is recommended. Use dim lighting, and cover their tank well, as they are excellent jumpers and are susceptible to cold air!
  • Temperature: 23-28 °C
  • pH: 4-6
  • Hardness: 0-10 NK°
  • Lifespan: 3-5 years

Description: Betta persephone has a slender, brown, slate gray, greenish black or bluish black body. The unpaired fins are blue (sometimes with a flush of red in the fin membranes), and the pelvic fins may be uniformly dark or red with white tips. The iris of the eye is iridescent blue. Because of its restricted natural range, the fish is added to the IUCN Red List of Threatened Species as Critically endangered. This is why its aquarium breeding is so important. The fish tolerates hard water, but does not grow well or spawn in these conditions, even with abundant space.

Males are a little larger than females, and more colorful during spawning, also they develop more extended fins as they mature. The tank should have a tight cover as the fry need access to a layer of warm, humid air or the development of the labyrinth organ can be impaired. Bubblenest builder, the male may use floating plants or floating plastic tube for refuge and build its nest in the tube or outside and adjacent, or he may select a sunken tube, Male will not tolerate the female in the vicinity of the bubblenest until it’s done, so they should be separated during this time. Just before spawning the female’s body become pale with dark bars on the flanks. During spawning the male and female will embrace each other, and while the female releases the eggs, the male fertilises them. The male then transfers them to his nest while the female recovers any that fell. Spawns number about 40 eggs, and the fry initially feed on infusoria or artificial plankton rotifer, before they take live brine shrimp nauplii. The surfaces of the dried leaves and live vegetation generate gliding protozoa, and no other infusoria should be necessary. Fry can be left with the parents and with previous spawns in a family tank, because cannibalism seems not to occur. Growth is slow, and maturity is attained in 9 months, at which time the males may become territorial.
