Obligate air-breathing (Ref. 126274); Found in extreme environments, from anoxic conditions (slack water zones bordered by dense vegetation) (Ref. 35381) to slightly turbid but free flowing streams (Ref. 11225). When the biotope becomes dry, it can move out of the water, due to its ability to breathe intestinally, in order to find another aquatic environment (Ref. 35381). Feeds at night on fish, insects and plant matter (Ref. 7020). Juveniles feed on rotifers, in addition to the micro-crustaceans and aquatic insect larvae they find when digging into the substrate (Ref. 35381). During reproduction, the male's belly turns orange and its pectoral spines become longer and thicker. The male builds a bubble nest with some floating plants, strongly guarding it after the female lays down her eggs (up to 120) (Ref. 35381). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 120 cm (Ref. 51539).

Builds a nest of air bubbles coated with saliva on the underside of a large leaf. Eggs are attached to the nest and are guarded by the male. Eggs hatch in 4 to 6 days. 南美洲: 布宜諾斯艾利斯， Argentins 大多數 Cis-安第斯山脈南美洲河流域北方。
