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).
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生
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.
