背棘 (總數): 0; 背的軟條 (總數): 6-8; 臀棘 0; 臀鰭軟條: 8 - 11; 脊椎骨: 38 - 43
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).
出現在流動緩慢又茶色的溪流通常在沙地。 也發現於沼澤，小的池塘與路傍溝渠。 捕食小的昆蟲，水生昆蟲幼生與細小的甲殼動物。 繁殖被伴隨著冬天雨。 雄性承擔一個明亮的彩色斑紋在那繁殖季節的初始。 夏眠是有可能的當許多水體在那一個這種被發現是短暫存在的.(參考文獻 33842)

50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00205 - 0.01170), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.0 ±0.00 se; based on food items.
Generation time: 0.4 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回復力 (Ref.
