I believe that is Oreochromis niloticus, with distinct similarities of the dorsal fin, pectoral and anal fin. The confusion arises from the clear separation of the caudal fin into two parts  which can be seen to be more of natural rather than result from possible accidents.

definitely not niloticus and doesn't look like an Oreochromis. More like Coptodon. In fact the tail looks like C. rendalli, but you need to check which ones occur in that area

I would also go for C. rendalli.

to me,it seems to be O. niloticus

It seems to be Coptodon rendalli.
