The Canary Blenny is also known as the Oualan Forktail Blenny or Canary Fang Blenny. This Canary Blenny is aptly named due to its vibrant yellow. Males tend to be larger than females, and they experience an array of color variations during breeding.nnnnThis blenny requires a tank size of at least 30 gallons filled with live rock for hunting and grazing to flourish. It is best to have just one per tank, unless a breeding pair. If the fish is attacked it responds by slicing into the attacker's mouth. The Canary Blenny is considered venomous and should be handled carefully in the presence of children who have access to tank.nnnn nnnnCanary Blenny's diet should consist of minced crustacean flesh as well as mysis, vitamin enriched brine shrimp and frozen herbivore dishes.nnnn nnnnApproximate Purchase Size: Small: 1-1/4" to 2-1/2"; Medium: 2-1/2" to 3-1/4"; Large: 3-1/4" to 4"

Canary Blenny – Yellow Fiji Meiacanthus oualaunensis Reef Fish

Canary Blenny; Yellow; Fiji - Meiacanthus oualaunensis displays a solid yellow body that contrasts sharply against reef rock and darker substrates. Unlike many bottom-dwelling species, this blenny hovers in open water, then quickly returns to rockwork. It performs consistently in stable reef systems found across our saltwater fish collection, where established rock structures support grazing and shelter. Movement defines this species. It shifts between hovering and short, darting bursts, creating constant activity without disrupting tankmates. Within the marine blennies category, it fills a mid-water niche while still relying on rock for security. A 30-gallon setup with tight lid coverage prevents jumping and supports long-term stability. However, house it alone unless you introduce a confirmed pair.

Temperament and Tank Compatibility

This species remains manageable in community setups, but it defends itself when threatened. It uses a venomous bite as a deterrent, not as a primary behavior. Therefore, avoid aggressive tankmates and limit similar-shaped fish in smaller systems.

Feeding Strategy and Diet

Keep the diet varied to maintain health and color. Feed mysis shrimp, enriched brine shrimp, and finely chopped meaty foods. In addition, include algae-based foods and spirulina to match its omnivorous needs. Feed smaller portions multiple times daily for consistent energy.
