Ptychochromoides vondrozo is a critically endangered species of cichlid endemic to the Mananara-sud river and its tributaries near Vondrozo in southeastern Madagascar. These are deep and moderate to fast-flowing. Its entire range covers less than 100 square kilometres (39 sq mi), which makes it highly threatened from continued sedimentation caused by deforestation. It is also threatened by other species that have been introduced to the region. It reaches a length of 20.4 centimetres (8.0 in) SL.
