The Otjikoto Tilapia, also called Lake Guinas Tilapia, is found naturally in only two small lakes in
Namibia, one of Africa's driest countries. Despite its common name, it is said to be native only to Lake Guinas and introduced
more recently to Lake Otjikoto.
The tilapia can reach 14cm in length. Those in Lake Guinas vary somewhat in appearance, but the differences
are not accounted for by age/gender.
Both parents guard and tend their eggs and fry. Critically endangered, threats include ground water
extraction and introduction of non-native fish.
