Ptychochromis is a genus of cichlids endemic to rivers and lakes in Madagascar. One species (P. grandidieri) can also be seen in brackish water.[1] Most species in this genus are threatened, and P. onilahy is probably extinct.[1] Most reach a length of 15 to 20cm, but P. insolitus reaches 25, while P. grandidieri and P. oligacanthus reach 35 and 20cm respectively. The largest species was P onilahy which may have reached as much as 45cm if reports of fishermen are to be believed.[1][2]

Species[]

There are currently 10 recognized species in this genus:[2]

Additionally, cichlid from the eastern Anosy Region in far southeastern Madagascar may actually represent an undescribed species, popularly known as Ptychochromis sp. "Manampanihy".[1]
