Common name: Green Canary Blenny

General information

The Tonga Fang Blenny, Meiacanthus tongaensis, is a small, colorful fish known for its distinctive elongated body and fang-like teeth. These blennies are part of the family Blenniidae and are native to the tropical waters of Tonga in the Pacific Ocean. They are notable for their ability to deliver a mild venom through their fangs, a unique adaptation for defense and competition.

Care

Tonga Fang Blennies are relatively easy to care for but require a well-established aquarium with plenty of live rock for hiding and grazing. They are generally peaceful but can be territorial with their own kind or similar-looking fish. A varied diet of meaty foods and marine algae will help maintain their health and vibrant colors.

Reproduction

In the wild, these blennies are oviparous, with males often displaying to attract females and encourage them to lay eggs in their territory. The male then guards the eggs until they hatch. In captivity, breeding Tonga Fang Blennies can be challenging, but with the right conditions, it is possible to observe their fascinating mating behaviors.

Habitat

Tonga Fang Blennies are found in shallow reef environments where they inhabit crevices and rubble. They are adept at darting in and out of tight spaces, which provides them with protection from predators and allows them to ambush small prey.
