Crater Lake Populations
Some specimens reportedly collected from Lake Tschungruru in Tanzania were identified as O. lidole by Trewavas. This lake appears to be the Kiungululu Crater (9°18′24.06″S 33°51′54.31″E), which is situated at an altitude of around 450m above the present surface of Lake Malawi. How they got there is a mystery. Some of these fish were sexually mature at sizes of 14–17 cm, which is much smaller than mature fish in Lake Malawi. Subsequently, smallish mature specimens were also collected from Lake Kingiri, which is only about 50m higher up than the main lake (9°25′07.67"S 33°51′29.29″E).
