Corematodus shiranus

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.^[1]
