Facultative air-breathing in the genus (Ref. 126274); Occur in slow-running, tea-colored streams usually in sandy areas. Also found in swamps, small ponds and roadside ditches. Also lives in the vegetated shallows of some freshwater lakes. Water is typically acidic (pH 4.5-6.5) and darkly tannin-stained. An inhabitant of temporary waters, capable of aestivating in damp bottom sediments over summer. Spawning habits similar to G. munda. Most individuals perish after their first spawning (Ref. 44894). Feed on small insects, larvae of aquatic insects and micro-crustaceans. Breeding is associated with winter rains. Males take on a bright color pattern at the start of the breeding season (Ref. 33842).
