Body shape (shape guide): fusiform / normal.
Occurs in ponds, lakes, marshes, muddy and sandy pools and backwaters of rivers (Ref. 5723). Feeds mainly on plant material but also on small larvae of insects. Its occurrence is related to those of the bivalve Anodonta cygnea and other freshwater mussels (Ref. 30578). Known for its habit of laying its eggs in the mantle cavity of freshwater mussels (Ref. 1739). Reproduction takes place from April to June (Ref. 30578).
Hides eggs in live invertebrates such as mussels, crabs or ascidians. The female develops a conduit ovipositor by which it deposits its ovules between the gills of the bivalve. The male then comes to deposit its seed close to the respiratory opening of the bivalve; at the interior of which fertilization takes place. The male keeps the eggs and alevins until they leave the refuge. In exchange, the fish rids the bivalve of its parasites (Ref. 30578). The young leave the mussel about 28 days after hatching, having reached a length of about 10 mm (Ref. 41678).
