Cette espèce apprécie plus particulièrement les zones à fort courant
Description
Ce poisson de la même famille que les mulets peut dépasser les 40cm.
C'est localement le seul mulet qui est présent en eau douce et qui remonte les rivières, les autres espèces restant généralement cantonnés aux eaux saumâtres des embouchures, étangs et lagunes.
L'espèce est indigène à l'Ouest de l'océan Indien.
Alimentation
Le chitte se nourrit surtout d'algues et de détritus, mais il peut également varier son alimentation avec de petits invertébrés voire de petits poissons.
Habitat
Cette espèce qui apprécie les forts courants n'hésite pas à remonter assez haut dans les rivières, à condition qu'il n'y ait pas de cassé trop important. Elle apprécie les eaux claires et oxygénées.
Reproduction
L'espèce serait catadrome ; les adultes retourneraient directement en mer pour se reproduire.
