Environment / Climate / Range
Freshwater; benthopelagic; pH range: 6.0 - 8.0; dH range: 5 - 19. Tropical; 24°C - 30°C (Ref. 1672), preferred ?; 22°N - 8°N, 99°E - 107°E
Asia: Mekong basin.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.5 cm TL male/unsexed; (Ref. 12693); max. reported age: 2 years (Ref. 12193)
Occur in standing waters of floodplains, canals, rice paddies (Ref. 12693) and medium to large rivers (Ref. 12975). Feed on zooplankton, mosquito and other insect larvae (Ref. 12693). Air breather and bubble nest builder. Used in behavioral studies (Ref. 4537). Males will fight each other. The many colorful varieties are popular aquarium fish, however, the holding of the males in very small containers should be discouraged (Ref. 1672). Aquarium keeping: sexes should be kept separate unless for mating, and that only one female should be brought into the breeding tank measuring about 20-30 L (http://www.kampffischnet.de).

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.41 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (tm<1; multiple annual spawning; Fec to 390).
Vulnerability (Ref. 59153
