Genus
Common name: Signal Blennies
Scientific name: Emblemaria
Emblemaria, commonly known as Signal Blennies, is a genus of small, colorful blennies found in the Western Atlantic. They are known for their unique signaling behavior, where males display their dorsal fin to communicate with females or rivals. These blennies are popular in the reefkeeping hobby due to their interesting behaviors and compatibility with other reef inhabitants. They require rockwork or rubble to hide and forage in, and a varied diet of small crustaceans and zooplankton. Observing their natural signaling behavior can be a fascinating aspect of keeping Signal Blennies in a home aquarium.
