Overview
Meiacanthus smithi Klausewitz, 1962 is a combtooth blenny of the family Blenniidae, commonly called Smith's fangblenny. According to FishBase it reaches about 8.5 cm in total length and occurs in the Indo-West Pacific. Sexual dimorphism is present in this species.
Taxonomy
- Family: Blenniidae
- Genus: Meiacanthus
- Scientific name: Meiacanthus smithi Klausewitz, 1962
Habitat
FishBase records this species from the Indo-West Pacific, including northern Sri Lanka and the western Java Sea, with reports from southeast India. It inhabits coastal and inner reef environments at depths of about 1 to 20 m, where juveniles usually occur alone and adults are occasionally found in pairs.
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, with demersal adhesive eggs attached to the substrate by a filamentous pad. The larvae are planktonic and occur in shallow coastal waters.
Compatibility
It is a peaceful, bottom-associated fish. 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. The species is used in commercial fisheries and the aquarium trade.
Breeding Smith's Fang Blenny (Meiacanthus smithi)
Overview
Meiacanthus smithi (family Blenniidae), the disco or Smith's fang blenny, reaches about 8.5 cm total length and lives on coastal and inner reefs of the Indo-West Pacific, recorded from northern Sri Lanka, the western Java Sea and southeast India at depths of 1-20 m. Like other Meiacanthus it carries venomous canine fangs used defensively, and it mimics juveniles of the bream Scolopsis bilineata.
Sexing
FishBase records sexual dimorphism in this species, and spawning involves distinct pairing of a single male and female. Outside spawning, juveniles are usually solitary while adults are occasionally seen in pairs, so a settled male-female pair is the basis for any breeding attempt.
Breeding Setup
A mature pair needs a peaceful reef-type system with abundant rockwork, crevices and small enclosed cavities that can serve as a nest site, matching the sheltered reef habitat described for the species. Stable tropical reef parameters within the ranges in the linked species record support spawning readiness.
Spawning Behavior & Trigger
The species is oviparous and spawns as distinct pairs. The female deposits eggs inside a chosen cavity where they are fertilised by the male; this paired, nest-based pattern is consistent across captive-bred Meiacanthus and is why the genus has become a reliable aquaculture target.
Egg & Fry Care
Eggs are demersal and adhesive, attached to the substrate by a filamentous adhesive pad or pedestal, after which the larvae hatch as planktonic forms found in shallow coastal waters. Commercial producers such as ORA have established captive-breeding lines for Meiacanthus fang blennies, confirming that the planktonic larvae can be reared through to settlement with dedicated larval systems and live foods.
Common Challenges
The main difficulty is rearing the small planktonic larvae, which require appropriately sized live prey and clean, stable larval-rearing conditions. The defensive venomous fangs also call for careful handling of broodstock during net transfers and tank maintenance.
