The Magnificent Foxface (Siganus magnificus), also known as the Magnificent Rabbitfish, is a distinctive rabbitfish native to the eastern Indian Ocean. Its combination of a dark facial mask, broad pale area behind the head, finely patterned body and contrasting yellow, orange and dark fin coloration makes it one of the most recognizable members of the rabbitfish family Siganidae.

The accepted scientific name is Siganus magnificus (Burgess, 1977). The species was originally described as Lo magnificus, but Siganus magnificus is the currently accepted classification. World Register of Marine Species

Its natural distribution is comparatively restricted. FishBase records the species from Thailand, including the Similan Islands, south to Java, Indonesia. The current Catalog of Fishes describes its distribution as the eastern Indian Ocean, including the Andaman Sea, Myanmar, and western Sumatra and Java in Indonesia. A 2026 scientific paper also documented voucher-confirmed specimens from western Sumatra. Your supplied Indonesian origin is therefore consistent with the documented range. FishBase

In nature, Magnificent Foxfaces inhabit coral reefs at approximately 2–30 meters (7–98 feet). Adults are commonly found in pairs, although solitary individuals occur, while juveniles tend to remain secretive among corals. FishBase

The species feeds naturally on algae and small invertebrates, making vegetable matter an important component of its aquarium diet. FishBase records a maximum length of 24 cm standard length, approximately 9.4 inches. FishBase

Like other rabbitfishes, the Magnificent Foxface possesses venomous dorsal and anal fin spines. FishBase specifically documents the spines of S. magnificus as venomous. The fish should therefore be handled carefully and never grasped directly by hand. FishBase

This Indonesian specimen is offered as one of Dr. Mac’s Quarantined and Conditioned Fish.

Care Guide

Scientific Name: Siganus magnificus (Burgess, 1977)
Common Name: Magnificent Foxface
Other Common Name: Magnificent Rabbitfish
Family: Siganidae
Origin: Indonesia
Availability: Conditioned & Quarantined
Care Level: Moderate
Temperament: Generally peaceful; may be territorial with similar rabbitfish
Reef Compatibility: Reef compatible with caution
Minimum Aquarium Size: 125 gallons recommended
Maximum Recorded Size: 24 cm SL / approximately 9.4 inches FishBase
Diet: Primarily algal grazer/omnivore; algae and small invertebrates are documented natural foods FishBase
Temperature: 75–80°F
Specific Gravity: 1.023–1.026
pH: 8.1–8.4

Aquarium Requirements: Provide substantial open swimming space along with established rockwork offering shelter and natural grazing surfaces. This corresponds well with the species' natural coral-reef habitat. FishBase

Diet and Feeding: Plant material should form a substantial part of the aquarium diet. Offer marine algae, nori and quality algae/spirulina-based preparations along with a varied selection of appropriate marine foods. This reflects the scientifically documented natural diet of algae supplemented by small invertebrates. FishBase

Temperament: Generally peaceful toward unrelated fishes. Adults naturally occur in pairs as well as individually, but rabbitfish can show territorial behavior toward similar-looking fishes in confined aquarium conditions. FishBase confirms the natural pair-forming behavior of adults. FishBase

Reef Compatibility: Reef compatible with caution. The species naturally consumes algae and small invertebrates, so I would not characterize it as unconditionally reef safe. A well-fed individual may coexist successfully in many reef systems, but behavior around sessile invertebrates should be monitored.

Venomous Spines: Use caution when handling or working around this fish. The dorsal and anal fin spines are venomous. This is a defensive feature rather than aggressive behavior, but accidental envenomation can occur if the fish is handled carelessly. FishBase

Natural Habitat: Coral reefs of the eastern Indian Ocean at approximately 2–30 meters.

The Pacific East Conditioning System

Every fish undergoes observation, conditioning
and proactive treatment before release

step-1_0ccf2c54-4a3e-4896-bdc4-89f238123f09

New arrivals are acclimated,
and inspected

step-2_400b411d-17ae-4476-b2bf-ca4214bf3432

We proactively treat fish during conditioning rather than simply holding them

step-3

Fish are closely monitored for feeding response, behavior and overall health.

step-4

Fish are transitioned onto prepared foods and conditioned for aquarium life.

Arrival and release dates help verify proper holding and conditioning time

"A properly conditioned fish adapts better, feeds more consistently, and has a stronger transition into aquarium life" - Dr. Mac

Order FAQs  

About Our Facility

Q: Are your corals aquacultured?
A: Yes. Many of our corals are grown in our Maryland Certified & Licensed Coral Aquaculture Facility.

Q: Why choose aquacultured corals?
A: Aquacultured corals are:
- More sustainable
- Better adapted to aquarium life
- Typically hardier than wild specimens

Q: Who selects and grows your corals?
A: Our corals are grown and curated by Dr. Mac a Board Certified Veterinary Pathologist with decades of hands-on reef experience.

Ordering & Shipping

Q: What does WYSIWYG mean?
A: “What You See Is What You Get.” The exact coral shown in the photo is the one you will receive.

Q: Can I request a specific color or variation?
A: For WYSIWYG items, what’s pictured is what you get. For non-WYSIWYG items, we do our best to match color and size, but natural variation occurs.

Q: Can I combine multiple orders to save on shipping?
A: Yes—contact us before shipping and we’ll consolidate when possible.

Q: How are corals and fish shipped safely?
A: We use insulated boxes, temperature control (heat/cold packs), and overnight delivery to ensure safe arrival.

Q: What days do you ship?
A: Typically Monday–Wednesday to avoid weekend delays.

Q: Do I need to be home for delivery?
A: Yes—someone should be available to receive livestock immediately.

Q: What if my coral or fish arrives dead (DOA)?
A: Contact us within a specified timeframe (e.g., 2 hours) with clear photos, and we will resolve it quickly.

Q: What voids the guarantee?
A: Missed deliveries, improper acclimation, or delays beyond our control.

Live Arrival Guarantee

Q: What if my coral or fish arrives dead (DOA)?
A: Contact us within a specified timeframe (e.g., 2 hours) with clear photos, and we will resolve it quickly.

Q: What voids the guarantee?
A: Missed deliveries, improper acclimation, or delays beyond our control.

Acclimation & First 24 Hours

Q: How do I acclimate new livestock?
A: Float to match temperature, then drip acclimate before placing in tank.

Q: Should I dip corals before adding them?
A: Yes but be careful, coral dips help prevent pests but use caution. Certain corals might benefit from a short quarantine period instead of a dip so as to further stressing them.

Q: Why does my coral look closed or stressed?
A: This is normal after shipping—most corals open within 24–72 hours.

Aquarium Setup & Compatibility

Q: Where should I place my coral in the tank?
A: Placement depends on the coral type (LPS, SPS, soft). Lighting and flow requirements vary—check each product description.

Q: Can different corals touch each other?
A: Many corals have sweeper tentacles and can sting neighbors. Always allow space.

Q: How fast will my coral grow?
A: Growth depends on species, lighting, water quality, and feeding.
