Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 6.0 - 8.0; dH range: 5 - 19; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 22°C - 25°C (Ref. 1672)

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.6 cm SL male/unsexed; (Ref. 36377)
Frequently occurs in flooded savannas of the coastal zone (Ref. 27188). Feeds on worms, crustaceans and insects (Ref. 7020). Quite popular among aquarists who breed it without difficulty. Males are larger and more colorful, possessing more distinctly more elongated unpaired fins (Ref. 35237). Aquarium keeping: several females for one male; minimum aquarium size 80 cm (Ref. 51539).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
During spawning the female changes its color to a chess-board pattern, which is apparently recognized by the young. Only the female takes care of the (up to 300) eggs and young, the male may defend the larger territory (Ref. 40602).
