Acei cichlid (Pseudotropheus Acei) also known as Yellow Tail Acei is from the Northwestern coast of Lake Malawi from the Bandawe Point to Ngara in Zambia, Africa. These fish are beautiful to look at with their striking yellowfins and slender blue body.
It is not easy to differentiate between the males and females in these fish. The males have egg spots on the back edge of their anal fins, while the females do not.
This can be one of the ways to tell the gender apart.
Acei cichlids are not fond of very bright lighting. As such, their aquarium should not have too much glare.
They mostly live in shallow waters, but sometimes go towards the surface, which is uncommon for the Mbuna cichlids.
Regan first discovered them in 1922, and it was originally believed to be a Pseudotropheus, and then it was changed to Gephyrochromis and then back again to Pseudotropheus.
When it is in the lake, a school of around 30 to 50 individuals around a large log is a common sight of these fish. In the rocky areas though, only about 3-10 would be found.
