Which of the following were the unique animals of Lake Victoria in East Africa driven to extinction following the introduction of the Nile perch into the lake?

The introduction of the Nile perch (Lates niloticus) into Lake Victoria in East Africa is believed to have contributed to the decline and extinction of several native fish species, particularly the smaller cichlids that were unique to the lake. The decline of these native fish species, in turn, affected other organisms in the food web that relied on them, including birds and other fish-eating animals, such as otters.
