Adults inhabit flowing water from small creeks and streams to the shallows of large and fast flowing rivers (Ref. 7335). Prefer rocky habitats and finds sanctuary in the various cracks and crevices provided by this type of environment (Ref. 7335), or among roots and debris (Ref. 44091). They occur in warm pools of springs and their effluents (Ref. 7020). Feed on worms, crustaceans, insects, fish and plant matter (Refs. 7020; 44091). Also used in behavioral studies (Ref. 4537). Approximately 100-150 eggs are deposited and are vigorously guarded and cared for by both male and female (Ref. 44091). A popular aquarium fish which requires high temperature to maintain itself in an environment, e.g. artificially heated waters of power stations. Aquarium keeping: in pairs; minimum aquarium size 80 cm (Ref. 51539).
成魚棲息於來自小溪與溪流到的流動的水大與快速流動的河的淺灘。 (參考文獻 7335) 在各種不同的裂縫與由這類型的環境 (參考文獻 7335) 提供的裂隙中偏愛岩石的棲息地與發現庇護所, 否則在根與殘礫之中.(參考文獻 44091) 他們出現在泉水與其溢流的溫暖水池。 捕食蠕蟲，甲殼動物，昆蟲，魚與植物 (參考文獻。 7020; 44091)。 也被用於行為的研究。 (參考文獻 4537) 需要高的溫度在環境維持它本身的一個受歡迎的水族館魚, 舉例來說人工地加熱.發電所的水域。 水族館保持: 成對; 水族館最小體型 80 公分.(參考文獻 51539)
Life cycle and mating behavior

Lays eggs on cleaned surfaces of rocks. Parents incubate eggs and guard young. Tends and fans the embryos and free embryos and transfers them several times into new pits excavated in the bottom using its mouth (huddling) (Ref. 34155).
Dark cavities are preferred as nests to conceal the brood and make them less conspicuous to visual predators (Ref. 38966). When in caves, single entrances are favored to reduce the probability of intrusion and are probably more manageable for the females in terms of defending their brood (Ref. 38966). Approximately 100-150 eggs are deposited and are vigorously guarded and cared for by both male and female (Ref. 44091).中美洲: 太平洋斜坡, 從瓜地馬拉到哥斯大黎加 (Tarcoles 河); 來自宏都拉斯 (Aguan 河) 到巴拿馬 (Guarumo 河) 的大西洋斜坡.
