Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 7.0 - 8.0; dH range: 9 - 20. Tropical; 21°C - 36°C (Ref. 36880)
Central America: Atlantic slope, from the Patuca River (Honduras) to the Matina River (Costa Rica); Pacific slope, from the Guasaule River (Nicaragua) to the Tempisque and Bebedero rivers (Costa Rica)(Ref.36377). Discovered in 1991 in the hot spring at Heviz (Balaton, Hungary) where it is established (Ref. 59043).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 17.0 cm TL male/unsexed; (Ref. 1672)
Inhabits lakes and swampy areas with muddy bottoms. Feeds on considerable ooze, detritus and filaments of algae (Ref. 36880). Forms pairs; both sexes territorial. Tolerant of high temperatures and able to survive in small water bodies during dry periods. (Ref. 59043).
Female tends the clutch. The larvae were attached to aquatic swimming plants because most oxygen is near the surface of the pool. Later female looks after the young, male defends the territory. This updates previous information from Ref. 1672.
