This species is distinguished from its congeners in having the following characters: maxilla short 0.70-0.77 times in anal fin base; head large 2.7-2.9 times in SL; male with 6-7 diffused dark bars along sides, covering only upper half of body; female with an irregular ocellus on dorsal fin, its black spot half-moon shaped, smaller than a pupil; eye 1-1.2 times in anal fin base; postdorsal-postanal 0.9-1.1 times in caudal peduncle length; anal fin usually smaller than its congeners, 3-3.9 times in head length; teeth absent on 4th ceratobranchial; dorsal fin inserted behind pelvic origin; nuptial males violaceous blue (Ref. 26729).
這種被與它的同類區分有下列的特徵: 顎骨短 0.70-0.77個倍臀鰭基底; 頭部大的 2.7-2.9 標準體長比率; 雄魚有被擴散深色的橫帶的 6-7 沿著側邊，覆蓋只有身體的上半部; 在背鰭上母魚有一個不規則的眼狀斑, 它的黑色斑點半月的形狀, 比一個瞳孔更小; 眼 1-1.2 倍臀鰭基底; 後背的-肛門後的 0.9-1.1 倍尾柄長度; 臀鰭通常比它的同類更小, 3-3.9 倍頭長; 齒在第 4個角鰓骨上不存在; 背鰭插在腹鰭起源後面了; 求偶的雄性 violaceous 藍色.(參考文獻 26729)
The springs at Ojo Charco Azul (= Barreno) are part of the Bolsón de Sandia complex, at 1600 m above sea level, and at the foot of Sierra Montelongo Pedregoso. The area is semiarid, with cacti other succulents; a densely woody area of cedar around the springs, except on the eastern side. Formerly the water was crystal clear at 19-20°C, but recently after depletion, the water is brown. Aquatic vegetation includes Ceratophyllum, Potamogeton, Typha, Eleocharis, Lemna, Utricularia, Scirpus, and Chara; crayfish Cambarellus sp. was observed. The bottom is loamy or muddy (Ref. 26729). Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139).
泉水在 Ojo Charco Azul(= Barreno) 是而在呈齒狀起伏的山脈 Montelongo Pedregoso 的腳的在 1600 公尺上方海平面的 Bolson de 西瓜複合體的部份。 區域是雨量非常的少, 藉由仙人掌其他的多汁; 一個西洋杉的濃密木本區域泉水左右, 除.在東邊上之外。 從前水在 19-20 °C 是透明清澈的, 但是最近在消耗之後, 水是褐色。 水生植物包括 Ceratophyllum ， Potamogeton ， Typha ， Eleocharis, Lemna, Utricularia, Scirpus, 與 Chara; 小龍蝦 Cambarellus sp. 被觀察。 底部是盧拇或泥濘的。 (參考文獻 26729) 不是一個季節性的鱂科魚類。 在水族館非常難以維持。 (參考文獻 27139)
