📖 Overview

A short-lived species which inhabits both flowing and stagnant shallows with abundant vegetation and detrital substrate. Spawns in March and April . Feeds on invertebrates, mainly on amphipods and copepods. Females may spawn more than once during a season. Up to 600 eggs are spawns by several females in a single nest. Eggs (2.4 x 0.9 mm) are spawned in a cavity (often inside standing, broken reeds); these are cleaned and guarded by the males. The eggs hatch probably in one day, larvae living on the bottom; both male and female dying shortly after spawning.
