Pseudotropheus flavus is a striking mbuna cichlid from Lake Malawi, known for its bright yellow body and bold, energetic behavior. Males display vivid golden-yellow coloration, while females may show slightly paler tones, creating a beautiful contrast in a community tank. Its compact size and active nature make it ideal for rocky Malawi setups.

Flavus is a moderately aggressive, territorial species, typical of mbuna cichlids. It thrives in rocky aquascapes with caves and hiding spots, where it can establish territories and interact dynamically with other mbuna species.
