Tilapia ID pls

[~T~]

Hi guys, can you ID these little tilapia that came free with some tiger barbs, the woman just couldn’t be arsed taking them back out of the bag I’m sure they are the common type introduced all over the place where I live (Vietnam), lakes here are full of them. I’ve just never properly IDd them. Thanks.

Maybe rendalli.

At the size yours are at the moment, it could be any of the genus Coptodon like rendalli, but they arevery hard to tell apart when young.
If it is rendalli, it will develop beautiful spotting on the head area when it matures.
Many Coptodon have that red area in the stomach and jaw area.
Here are a couple other choices, both probably feral in Viet Nam.
Coptodon zillii

Oreochromis niloticus

It could also be one of the Coptodon from lake Bermin, but I doubt they have become feral there, they are quite rare , and stay small, only about 7".

My bet is on redbreast - rendalli
Fun fish to catch
