Longnose Hawkfish

The Longnose Hawkfish (Oxycirrhites typus) is an unmistakable marine aquarium fish with an elongated, pointed snout and a striking white body covered in an intricate red crosshatch pattern. Its unusual shape and characteristic habit of perching on rockwork and coral branches give it a distinctive personality that stands out in both reef and fish-only aquariums. Rather than constantly swimming through the water column, this species often chooses an elevated perch from which it watches its surroundings and searches for passing prey.

In the wild, the Longnose Hawkfish occurs across a broad tropical range spanning the Indo-Pacific, Red Sea, Hawaiian Islands, and portions of the eastern Pacific. Adults are commonly associated with steep outer reef slopes, where they perch among gorgonians, black corals, and other branching structures exposed to current. Growing to approximately 5 inches, Oxycirrhites typus is a manageable but predatory saltwater fish that adapts well to established aquariums when provided with appropriate hiding and perching locations.

Although generally compatible with corals, its carnivorous feeding behavior makes it best classified as reef safe with caution. Small ornamental crustaceans and very small fish may be viewed as prey.

Tank Requirements

Provide an established saltwater aquarium with substantial rockwork, caves, ledges, and elevated structures that can serve as observation and resting points. Branching rock formations or sturdy coral structures are particularly suitable because Longnose Hawkfish naturally spend much of their time perched above the surrounding reef.

Despite their relatively sedentary appearance, adequate swimming room should remain between structures. Moderate to strong water movement can be provided, particularly around elevated perching locations, reflecting the current-swept reef slopes this species occupies naturally.

A tight-fitting lid or securely covered aquarium is strongly recommended. Hawkfish are capable jumpers and may leave an open aquarium when startled or during territorial interactions.

No specialized substrate is required. Long-term success depends more heavily on stable water quality, secure rockwork, appropriate tankmates, and numerous elevated resting locations.

Diet and Feeding

The Longnose Hawkfish is a carnivore that naturally feeds on small benthic and planktonic crustaceans. In captivity, it typically accepts a wide assortment of meaty marine foods.

Offer mysis shrimp, enriched brine shrimp, finely chopped shrimp, krill, chopped clam or other marine seafood, quality frozen carnivore blends, and appropriately sized sinking or slow-sinking marine pellets. Providing several different foods helps maintain good condition and encourages natural feeding behavior.

Feed once or twice daily, offering portions that can be consumed without leaving significant uneaten food in the aquarium. Newly introduced individuals may initially respond especially well to frozen or moving foods before becoming accustomed to prepared diets.

Temperament and Tankmates

Longnose Hawkfish are semi-aggressive, territorial predators but are generally less troublesome toward appropriately sized fish than many larger hawkfish species. They spend considerable time perched in preferred locations and may defend these areas from competitors.

Suitable tankmates include many clownfish, tangs, dwarf and larger angelfish, moderately sized wrasses, dottybacks, basslets, and other marine fish too large to be considered prey. Very small gobies, juvenile fish, and similarly tiny tankmates should be selected cautiously.

Small ornamental shrimp are particularly vulnerable and may eventually be eaten. Larger shrimp may fare better, but compatibility cannot be guaranteed.

For most aquariums, keeping a single Longnose Hawkfish is the simplest approach. Established pairs can be maintained under suitable conditions, but unrelated individuals should not simply be combined without adequate space and careful observation.

Reef Compatibility

Reef Safe: With Caution

The Longnose Hawkfish generally does not consume coral tissue and can be maintained successfully in many reef aquariums. Its primary reef-related concern is predation on mobile invertebrates rather than damage to corals.

Small ornamental shrimp and other small crustaceans may be hunted and eaten. Very small fish can also be at risk. Crabs and other suitably sized mobile invertebrates should still be monitored.

Longnose Hawkfish frequently perch directly on branching corals, gorgonians, and similar structures. While this behavior is natural and usually causes little harm, repeated perching may irritate particularly delicate specimens.

Aquarists keeping valuable ornamental shrimp or exceptionally small reef fish should consider the predatory nature of this species before introducing one.

Water Parameters

Temperature: 75–79°F
Specific Gravity: 1.024–1.026
pH: 8.1–8.4
Alkalinity: 8–12 dKH

Maintain stable, well-oxygenated seawater with consistent salinity and temperature. Avoid rapid parameter changes, as long-term stability is more important than continually adjusting the aquarium to achieve an exact number.

Common Considerations

• Reaches approximately 5 inches and requires an aquarium of at least 30 gallons with adequate structure and territory.

• Small ornamental shrimp, crustaceans, and very small fish may be treated as prey.

• Provide plenty of elevated rock ledges and branching structures for natural perching behavior.

• Use a tight-fitting lid or securely covered aquarium because hawkfish can jump when startled.

• Generally compatible with corals, but its predatory behavior toward mobile invertebrates makes it reef safe with caution.

Longnose Hawkfish (Oxycirrhites typus)

The Longnose Hawkfish is a standout reef fish with a distinctive elongated snout and an eye-catching red and white crosshatch pattern. Found perching among gorgonians and branching corals in the wild, they bring a mix of charm, color, and quirky behavior to any saltwater aquarium. Their alert expressions and perching habits make them a true favorite among aquarists.

Tank Requirements

Longnose Hawkfish do well in aquariums of 30 gallons or more, ideally with plenty of live rock, branching coral structures, or aquascaping that mimics their natural perching spots. A tight-fitting lid is important, as they are capable jumpers, especially when startled.

Unique Perching Behavior

True to their name, Longnose Hawkfish perch on rock ledges or coral branches, watching everything around them with keen awareness. Their long snouts help them probe into crevices for food, and their behavior is a constant source of entertainment for reef keepers.

Diet and Feeding

Carnivorous by nature, Longnose Hawkfish enjoy a protein-rich diet. Offer a variety of meaty foods such as mysis shrimp, brine shrimp, chopped seafood, and high-quality frozen blends. They generally adapt well to prepared foods and benefit from a varied feeding routine.

Tankmates and Behavior

Longnose Hawkfish are semi-aggressive and best kept with similarly sized or larger tankmates. While they are typically reef-safe with corals, they may pose a risk to small ornamental shrimp or very small fish. They are best housed solo unless kept in a large enough system to accommodate a mated pair.
