Compiled by Aquairi from published sources · Published · Updated
Overview
Meiacanthus oualanensis (Günther, 1880) is a combtooth blenny of the family Blenniidae. According to FishBase it reaches about 10 cm in standard length and is endemic to Fiji in the western central Pacific. The species name refers to the island of Ovalau in Fiji.
Taxonomy
- Family: Blenniidae
- Genus: Meiacanthus
- Scientific name: Meiacanthus oualanensis (Günther, 1880)
Habitat
FishBase records this species as endemic to the western central Pacific, specifically the waters around Fiji. It is a marine, reef-associated fish of tropical waters.
Tank requirements
- Minimum tank volume: 100 L (about 26 gal)
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- Carbonate hardness range (record): 8-12 °dGH
- Lifespan: 3-8 years (KB record)
Breeding
According to FishBase the species is oviparous and forms distinct pairs. Eggs are demersal and adhesive, attached to the substrate by a filamentous pad, and the larvae are planktonic, occurring in shallow coastal waters.
Compatibility
It is a peaceful, bottom-associated fang blenny. Suitable companions include clownfish, tangs, cardinalfish and wrasses, while large aggressive predators such as lionfish and triggers should be avoided.
Conservation status
IUCN Red List: Least Concern, assessed in 2009.
Breeding the Canary Fang Blenny (Meiacanthus oualanensis)
Overview
Meiacanthus oualanensis (family Blenniidae), the canary fang blenny, is known only from Fiji in the western central Pacific. FishBase gives a maximum length of 10 cm standard length, while Wikipedia cites a smaller figure of about 5 cm; it is a reef-associated member of the venomous-fanged Meiacanthus genus.
Sexing
FishBase records the species as oviparous with distinct pairing, so spawning depends on forming a settled male-female pair. As with related fang blennies, a compatible bonded pair is the prerequisite for reproduction in the aquarium.
Breeding Setup
House the pair in a calm reef-type aquarium with rockwork and small enclosed cavities suitable as a nest, in keeping with the species' reef-associated habitat. Stable tropical marine parameters within the ranges given in the linked species record support spawning.
Spawning Behavior & Trigger
Reproduction follows the Meiacanthus pattern of distinct pairing, with the female depositing eggs in a sheltered cavity that the male fertilises and guards. This cavity-nesting, paired strategy is shared across the genus and underpins its success in aquaculture.
Egg & Fry Care
Eggs are demersal and adhesive, fixed to the substrate by a filamentous adhesive pad or pedestal, and the larvae hatch as planktonic forms found in shallow coastal waters. Commercial captive breeding of Meiacanthus fang blennies by producers such as ORA shows these larvae can be reared through metamorphosis given dedicated larval systems and live foods.
Common Challenges
Rearing the planktonic larvae through their early stages is the principal hurdle, demanding correctly sized live prey and stable water quality. The venomous defensive fangs mean broodstock should be handled with care.
