Peacock Blenny

The Peacock Blenny is a visually stunning combtooth blenny that earns its name from the intricate, peacock-like pattern of iridescent blue-green spots and lines adorning its olive to brown body. Males are particularly spectacular during breeding displays, developing intensified coloration with brilliant blue facial markings and an elaborate head crest that they raise to impress potential mates.

A close relative of the popular Lawnmower Blenny, the Peacock Blenny shares the same dedicated algae-grazing lifestyle, spending its days hopping between rock surfaces and diligently scraping filamentous algae with its comb-like teeth. Found across a remarkably wide range from the Indo-Pacific to the Red Sea and Mediterranean, it is an adaptable species that thrives in various marine environments. In the aquarium, it is one of the most effective natural algae control agents available.

The Peacock Blenny is hardy, peaceful, and easy to care for, making it an excellent choice for beginner aquarists who want both beauty and functionality. Its constant grazing behavior keeps rockwork clean while its ornate patterning provides visual interest that many plainer algae-eating species lack. It is completely reef-safe and integrates well into community reef setups.
