Common name: Miter blenny

General information

The Banded Fang Blenny, scientifically known as Petroscirtes mitratus, is a small, colorful fish that is popular among reef aquarium enthusiasts. This species is known for its distinctive coloration, with vertical bands of black and yellow or blue, and a characteristic 'crown' of elongated dorsal fin rays that resemble a mitre, which is where its species name 'mitratus' comes from.

Care

Banded Fang Blennies are relatively hardy and can adapt to life in an aquarium. They require a tank with plenty of live rock for hiding and grazing on microalgae. These blennies are known to be jumpers, so a tightly fitting lid is essential to prevent escape. They are generally peaceful but can be territorial towards other blennies. A varied diet of meaty foods and marine algae will help maintain their health and coloration.

Reproduction

In the wild, Banded Fang Blennies are oviparous, with males often displaying to attract females and encourage them to lay eggs in a secure location. In the aquarium, breeding is less common, but with a well-established pair, spawning can occur. The male typically guards the eggs until they hatch.

Symbiosis

While not known for a specific symbiotic relationship like clownfish with anemones, Banded Fang Blennies have been observed picking parasites off larger fish in a mutualistic relationship where both parties benefit.

Habitat

Petroscirtes mitratus is found in shallow, tropical marine waters, often in coral reef environments or among mangroves. They are adept at navigating the complex structures of the reef, which provides them with protection from predators and abundant food sources.
