The Yellow Tail Acei is a striking fish with vibrant blue and yellow coloring. It’s active and adds a lot of visual interest to the tank. I’ve kept it with other mbuna, but I need to be careful with tank mates due to its aggressive nature. Feeding is straightforward with quality flakes and occasional live foods.

Great coloration and active behavior. The fish is slightly aggressive, so I made sure to provide plenty of hiding spots. It’s a captive-bred specimen, which is a plus for ethical sourcing. I’ve seen some white-finned variants in the wild, but this one has the classic yellow tail.

The fish looks beautiful and is a good addition to a Malawi mbuna tank. However, it can be territorial, especially during feeding times. I recommend keeping it with compatible species like Melanochromis. It’s not the easiest to maintain due to the water parameter requirements.
