Corematodus shiranus is a species of haplochromine cichlid fish native to Lake Malawi, Lake Malombe and the upper reaches of the Shire River in East Africa.

[1] It is an aggressive mimic of the chambo cichlids (Nyasalapia, a subgenus of Oreochromis) in both color pattern and swimming mode.

It is therefore able to approach unsuspecting schools of these species and rapidly take a mouthful of scales or fin.

[3][4] Due to overfishing, the chambo cichlid populations have drastically declined, adversely affecting C. shiranus, which was last reported in 1997 and might now be extinct.
