Description de l'espèce
Geographical Origin and Habitat: A marine species; the enclosure should provide stability, oxygenation, space and shelter consistent with its behaviour without turning one habitat description into a mandatory recipe.
Taxonomy and Morphology: The accepted scientific name is Siganus vulpinus; the verified classification records genus Siganus, family Siganidae, order Acanthuriformes. Historical names remain searchable as synonyms rather than separate species.
Social Behavior: Foxface Rabbitfish is normally kept as a single individual and does not require conspecifics. The minimum reference is one individual; sex, maturity and available space can require a more conservative composition. Observe access to food, resting behaviour, chasing and use of shelter. Isolation, persistent competition or aggression means the number, composition or environment needs to be corrected.
Coloration and Sexual Dimorphism: Colour and shape can vary with age, sex, physiological state and environmental conditions. Identification and sexing require recognized species-level characters; one appearance or photograph is not enough.
Soins, reproduction et cohabitation
Aquarium Setup: Foxface Rabbitfish needs an aquarium of at least 300 litres, sized for adult body size and a minimum group of one individual. Filtration, shelter and swimming room must match the species and the actual number kept. Volume alone does not make an enclosure suitable: tank shape and length, usable area, oxygenation and the ability to separate territories must reflect adult behaviour.
Diet and Feeding: The recorded diet is omnivorous. Offer appropriately sized foods varied within that category, and adjust quantity and frequency from actual intake, body condition and leftovers. One food or a fixed schedule is not suitable for every age and situation.
Water Quality: Maintain stable, well-oxygenated water appropriate to a marine species; the card's reference values are 24–27 °C, pH 8.1–8.4. Verify conditions with reliable tests and size maintenance and filtration to the actual load. Ranges are not automatic thresholds for treatment or rapid chemical correction.
Compatibility and Cohabitation: The cohabitation profile is reef-safe with caution, with a generally peaceful temperament. Keep at least one individual; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
Aquarium Breeding: The recorded reproductive profile is “oviparity”. Breeding should be attempted only with healthy adults, separation capacity and a plan for eggs or young. Do not treat unverified triggers, sex ratios or hatch times as universal for this species.
Risks and Diseases: Use a secure cover and close escape gaps. Fin spines are venomous and require suitable tools and protection. Prevent problems through quarantine of new arrivals, stable water, appropriate feeding and daily observation. Similar signs can have different causes, so check parameters, history and diagnosis before medication. Follow the product label and qualified aquatic-veterinary advice; there is no universal reduced dose for a species or family.

Profil de poisson
- Tempérament
- Peaceful
- Foxface Rabbitfish has a generally peaceful temperament. Insufficient space, an unsuitable social ratio or incompatible tankmates can substantially change observed behaviour.
- Régime alimentaire
- Omnivore
- They are quintessential herbivores that require a heavy daily intake of marine algae and vegetable matter. Provide them with a constant supply of dried seaweed (nori) attached to a clip. They will also happily accept spirulina flakes, herbivore pellets, and occasional meaty treats.
- Espérance de vie
- 10-15 years
- Taille adulte
- 25 cm
- Ratio des sexes
- Solitary
- Foxface Rabbitfish is normally kept as a single individual and does not require conspecifics. The reference minimum is one individual and must not be read as permission to overcrowd the aquarium.
- Fréquence d'alimentation
- Twice daily
- Offer them small amounts of food two to three times a day to simulate natural grazing. A constant supply of nori ensures they do not turn to picking at corals out of hunger. They are very active feeders and will quickly learn to beg for food when you approach the tank.
- Charge biologique
- High
- The Foxface Rabbitfish creates a significant bioload due to its large adult size and voracious appetite. They constantly process plant matter, resulting in a continuous output of biological waste. A well-established aquarium with an oversized protein skimmer is vital for maintaining high water quality.
- Courant
- Moderate
- Siganus vulpinus needs steady, moderate circulation distributed across the aquarium rather than a narrow, forceful jet. Large marine aquarium (Minimum 120 cm / 48 inches). Lots of well-established live rocks with crevices where it can hide during the night. This preserves useful water exchange while retaining calmer shelter for rest and feeding.
- Risque de saut
- Yes
- There is a moderate risk of jumping, especially during the initial acclimation period or if startled at night. Sudden changes in lighting can cause them to panic and dart towards the surface. Keeping a secure lid on the aquarium is always the safest practice.
- Reproduction
- Oviparous
- Breeding the Foxface in a home aquarium is considered impossible for the average aquarist. They are pelagic spawners that release their gametes into the open water column. The larval stage requires microscopic planktonic foods and very stable, large-scale systems to survive.
- Compatibilité et compagnons
- Reef safe with caution
- The cohabitation profile is reef-safe with caution, with a generally peaceful temperament. Keep at least one individual; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
- Niveau dans le bac
- Middle/Bottom
- They are extremely active swimmers that will constantly patrol the middle and upper levels of the tank. They require a large, open swimming area to stretch their fins and prevent stress. They also need large caves in the rockwork to retreat into when resting or frightened.
