Maturity: Lm ? range ? - ? cm
Max length : 16.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 36377)
臀棘: 3. Aequidens is very similar to Geophagus but is differentiated by the number of spines on the anal fin and the lacks of a lobule on the first branchial arch found in Geophagus; live specimens olive green, with eight obscure transverse bands on the body; numerous bright bluish-green lines on the cheek; males are more colorful and grow bigger than females; males blue in color during the reproductive season (Ref. 26543).
Aequidens 是非常類似 Geophagus 但是在臀鰭上被藉由棘的數字區別與那在第一個鰓弓上沒有一個小裂片發現於 Geophagus; 活體橄欖綠色的, 藉由在身體上的八個暗的橫紋; 在頰部上的很多的明亮藍綠色的線; 雄性更色彩鮮豔而且生長比雌性更大; 雄性藍色顏色在生殖的季節期間.(參考文獻 26543)
Inhabits turbid standing waters as well as clear free flowing streams (Ref. 11225). Feeds on worms, crustaceans and insects (Ref. 7020). Reproduces in captivity (Ref. 26543). Both parents guard the eggs and larvae (Ref. 7020). Has been used to control mosquito larvae (Ref. 40602). Aquarium keeping: in pairs; minimum aquarium size 100 cm (Ref. 51539).
棲息於混濁的不流動的水域以及清澈的自由流動的溪流.(參考文獻 11225) 吃蠕蟲，甲殼動物與昆蟲。 (參考文獻 7020) 繁殖在繁殖場。 (參考文獻 26543) 曾經用來控制蚊蟲幼生.(參考文獻 40602) 水族館保持: 成對; 水族館最小體型 100 公分.(參考文獻 51539)
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
In captivity, both male and female clean a rock which will be the spawning area. Eggs are laid on the rock by the female and fertilized by the male. Both male and female guard the eggs, which hatch in 2 to 5 days, and continue to look after the fry for some weeks (Ref. 7020). In cases of danger, the male protects its young by placing them inside its mouth (Ref. 26543).中美洲與南美洲: 千里達與委內瑞拉。
