Suggested Tank

Max Size

3.7 inches

Difficulty

Easy

Temperament

Peaceful

Description

A slender, mid-water fang blenny with a blue-grey head and forebody that blends into bright yellow at the rear, marked by a dark horizontal line and a black-edged dorsal fin. Peaceful and constantly active, it hovers in open water and darts into rockwork when startled, making it an excellent, hardy community reef fish that is rarely bothered by tankmates thanks to its venomous fangs. Provide plenty of swim room, ample rock for perching and refuge, a tight-fitting lid, and feed small meals several times daily; only house one per tank unless it is a proven mated pair, and avoid other similarly shaped Meiacanthus.

Reef Safe

Yes

Environment

The Blackline Blenny prefers a tank with plenty of hiding places, such as caves and rocks. It also needs a tank with a secure lid, as it is known to be a jumper.

Behavior

This fish is peaceful and tends to be a good community tank member. It is not known to be aggressive unless threatened. It spends much of its time hiding in rocks and caves, and it is known for its unique ability to "hop" along the substrate of the tank.
