Blackline fang blenny

The Blackline fang blenny (Meiacanthus nigrolineatus) is a small, distinctively colored fish primarily characterized by its bold, black lateral line contrasting against a lighter body color, which can range from pale to darker hues. Native to the Western Pacific Ocean, this species is recognizable by its elongated body and the presence of fangs as part of its dentition. Despite its striking appearance, the Blackline fang blenny is not particularly well-known in the aquarium hobby, catering more to enthusiasts interested in niche or specialized marine species.
