Conservation: Paretroplus tsimoly is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (EN) endangered (2020). Extensive deforestation of its watershed and the widespread occurrence of exotic species in the lower Betsiboka drainage notwithstanding, P. tsimoly is reasonably abundant in both its type locality and the neighboring Boinakely River. This appears due in large measure to the fact that unlike its lacustrine congeners, it has never been targeted by local gill net fishermen (Stiassny et al., 2001:40).
