The Maroon Clownfish (Premnas biaculeatus) is a vibrant and captivating maroon clown variant distinguished by its bright gold coloration that deepens with age. Reaching up to 6 inches, this species thrives in symbiosis with large sea anemones in Indo-Pacific coral reefs. While reef-safe with caution, its territorial nature requires careful tank management. With proper care, it can live 7 to 10 years, making it a striking and durable choice for experienced marine aquarists.
