Overview
Zebrasoma veliferum is a species in the family Acanthuridae. A large tang with a dramatically tall dorsal and anal fin that can be raised like a sail. Beautiful striped pattern in brown, yellow, and white. Grows to 40cm and needs a very large tank. Peaceful compared to other large tangs but territorial with conspecifics.
Taxonomy
- Family: Acanthuridae
- Genus: Zebrasoma
- Scientific name: Zebrasoma veliferum
- Other names: Pacific Sailfin Tang
- Origin: Indo-Pacific
Habitat
Widely distributed across the Indo-West Pacific from the Cocos-Keeling Islands to Tuamoto and from southern Japan to the Great Barrier Reef. Adults inhabit clear lagoons and seaward reefs to 30 m; juveniles develop a large barred sail-like dorsal fin that recedes proportionally with age.
Tank requirements
- Minimum tank volume: 600 L
- Temperature: 24-27 °C
- pH: 8.1-8.4
- GH: 8-12 °dGH
- Water flow: strong
- Adult size: 30-40 cm
- Lifespan: 10-20 years
- Difficulty: intermediate
Diet
Classified as herbivore. Recommended feeding frequency: 2x daily. In captivity, offer a varied diet appropriate to the species — quality prepared foods supplemented with frozen or live items of suitable size.
Compatibility
- Temperament: semi-aggressive
- Swimming level: middle
- Compatible tank mates: Clownfish, Wrasses, Angelfish
- Avoid with: Other Sailfin Tangs, Similar Tangs
Reef compatibility
Generally classified as reef-safe: does not feed on stony or soft corals, tridacnid clams or ornamental shrimps under normal conditions.
Breeding
- Breeding strategy: egg-scatterer
- Breeding difficulty: advanced
Sailfin Tang (Zebrasoma veliferum) Breeding Guide
Overview
The sailfin tang, Zebrasoma veliferum, is a large Indo-Pacific surgeonfish of the family Acanthuridae. It reproduces by pelagic broadcast spawning, releasing eggs and sperm into open water; the eggs and larvae are planktonic. Because the larval phase plays out in open ocean, the species is not bred in home aquaria.
Spawning Behavior & Trigger
Surgeonfishes generally spawn at dusk, often in groups but sometimes as pairs, ascending and releasing gametes into the water column for external fertilisation. Spawning is frequently linked to lunar periodicity. These behaviours depend on open-water space and aggregation cues that cannot be created in an aquarium.
Egg & Fry Care
For the sailfin tang the eggs are pelagic and hatch after about one day. The hatchlings develop into the transparent, drifting acronurus larva characteristic of tangs, which remains in the plankton for an extended period before settling on a reef. These larvae are fragile and require specialised micro-prey, so they cannot be reared under ordinary aquarium conditions.
Common Challenges
Surgeonfish aquaculture became possible only at research scale: the first captive breeding of any acanthurid was the yellow tang (Zebrasoma flavescens) by the Oceanic Institute in 2015, after roughly a decade of effort with cultured copepod prey. No comparable home-aquarium method exists for the sailfin tang.
