Margariscus margarita is almost identical to Margariscus nachtriebi but can be distinguished from this species by having larger scales and usually 50-62 lateral scales (Ref. 86798).
Inhabits pools of upland creeks and small rivers, and also ponds and lakes. Usually found over sand or gravel (Ref. 86798). Feeds on copepods, cladocerans, chironomids, beetles, filamentous algae, and Chara (Ref. 1998). Spawns during the spring (Ref. 1998).
成魚棲息於小溪與小河的水池, 也池塘與湖。 他們通常出現在沙地或礫石上面。 捕食橈腳類的動物，水蚤，寶刀魚，甲蟲，菌絲藻與 Chara 。 (參考文獻 1998) 在春天期間產卵。 (參考文獻 1998)
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
Spawning occurs in shallow rivers with moderate current, on sand or gravel. Males maintained territories 20.3 cm wide (at least 1.83 m apart from each other). A ripe female is driven onto the territory. The male places his pectoral fin beneath the female's body anteriorly, and his caudal fin placed over the caudal peduncle of the female. The pair vibrates and the eggs are deposited. Females spawn with different males.北美洲: 在加拿大南部與美國北部從大西洋的岸邊到西北地區南部, 東方的加拿大的英屬哥倫比亞與美國的蒙大納中的大西洋，哈得遜灣，五大湖與密西西比河流域; 南至維吉尼亞，密西根州，威斯康辛州與美國愛荷華州; 在密蘇里河流域上游。
