Description
The Blackfin Glass Blenny, Plagiotremus phenax, is a slender, elongated blenny known for mimicking the venomous Blackfin Fang Blenny. It has a somewhat translucent body with an orange stripe, and is characterized by its unique feeding behavior of nipping at the scales and mucus of other fish. Due to its specialized diet and nipping habits, it is considered a challenging species for the home aquarium.
