Festivum Cichlid (Mesonauta guyanae)

The Festivum Cichlid is a graceful and underrated South American species known for its tall, laterally compressed body and elegant swimming style. Often referred to as the “Flag Cichlid,” this fish displays subtle vertical banding and a calm, gliding presence that contrasts with more aggressive cichlids. Native to slow-moving Amazonian waters, Festivums are an excellent choice for aquarists seeking a peaceful yet visually striking centerpiece fish.

Festivum Cichlids are omnivorous and easy to feed:
