Learn about Oxycirrhites typus tank requirements, personality, and why this perching fish is a saltwater favorite. ## Species Overview The Longnose Hawkfish (*Oxycirrhites typus*) is one of the most distinctive small predators in the saltwater hobby. Its elongated, tapered snout -- roughly twice the length you would expect on a fish this size -- sets it apart from every other hawkfish species at a glance. Combined with its bold red-and-white crosshatch pattern, it looks more like a piece of living reef art than a functional ambush predator. That snout is not decorative. It is a precision feeding tool designed to probe into gorgonian branches and black coral thickets for the small crustaceans hiding inside. This species belongs to the family Cirrhitidae and is the sole member of its genus. Found across the Indo-Pacific from the Red Sea to the Gulf of California, the Longnose Hawkfish lives deeper than most of its cousins -- typically 10 to 100 meters down -- on steep outer reef slopes where gorgonian sea fans and black coral colonies grow in abundance. That depth preference is worth keeping in mind when designing its aquarium. | Field | Value | | ----------- | ------------------------ | | Adult size | 5 in (13 cm) | | Lifespan | 5–10 years | | Min tank | 75 gallons | | Temperament | Semi-aggressive predator | | Difficulty | Intermediate | | Diet | Carnivore | ### The Unique Morphology of *Oxycirrhites typus* No other hawkfish looks like this one. The elongated snout accounts for roughly a third of the fish's total head length and narrows to a fine point tipped with a small, upturned mouth. The body is white to pale cream, covered in a precise grid of red horizontal and vertical lines that cross to form a distinctive checkerboard or tartan-like pattern. Dorsal fin tassels -- the cirri that give the family its name -- are visible at the fin tips when the fish is relaxed. The red crosshatch patterning provides camouflage inside the branching architecture of gorgonians, where red and orange tones blend against the coral's pigmentation and the subdued light of deeper reef slopes. In a home aquarium under reef lighting, the same pattern reads as an exceptionally striking graphic print. > **Distinctive elongated snout** > > The Longnose Hawkfish's most recognizable feature is its dramatically extended snout, which is roughly twice as long as that of other hawkfish. This structure evolved to probe gorgonian branches and black coral thickets for hidden crustaceans. Handle newly purchased specimens carefully and inspect the snout for abrasion injuries during transport -- see the LFS checklist below. ### Natural Habitat: Gorgonians and Black Corals In the wild, *Oxycirrhites typus* lives almost exclusively in association with large gorgonian sea fans and black coral (*Antipathes* spp.) on steep outer reef walls and deep fore-reef slopes. It perches inside the branches rather than on top of them, using the structure as both camouflage and a vantage point. Water at these depths is cool, highly oxygenated, and subjected to strong, steady currents running along the reef face. Replicating this in captivity means providing structure the fish can perch inside or on top of -- branching live rock, artificial gorgonians, or even large leather coral colonies -- combined with decent flow and stable water quality. A tank that is too flat or too still will produce a hawkfish that hides rather than displays. ### Lifespan and Maximum Size Longnose Hawkfish typically reach five inches in a well-maintained aquarium. Some individuals approach six inches, making them meaningfully larger than [Flame Hawkfish](/species/flame-hawkfish), which top out around four inches. Expected lifespan with proper care is five to ten years, with specimens in stable, long-running reef systems sometimes exceeding that range. ## Water Parameters & Tank Requirements ### Ideal Parameters Despite their deep-water origins, Longnose Hawkfish adapt well to standard reef conditions. Maintain temperature between 72 and 78 degrees Fahrenheit, pH between 8.1 and 8.4, and specific gravity between 1.023 and 1.025. ### Longnose Hawkfish Water Parameters | Parameter | Target | Notes | | ---------------- | ----------------- | ----------------------------------------------------- | | Temperature | 72–78°F (22–26°C) | Stable is more important than hitting an exact number | | Salinity / SG | 1.023–1.025 | Use a refractometer, not a hydrometer | | pH | 8.1–8.4 | Standard reef range | | dKH (Alkalinity) | 8–12 dKH | Maintain stability for reef health | | Ammonia | 0 ppm | Any reading is toxic | | Nitrite | 0 ppm | Must be zero before stocking | | Nitrate | \<20 ppm | Weekly water changes keep this in check | ### Minimum Tank Size and the Jump Risk Factor The brief description calls for a 30-gallon minimum, and that is technically true, but it undersells how much better this species does in larger systems. A 75-gallon or larger tank gives the Longnose Hawkfish room to establish a territory, multiple perching sites across different height levels, and enough water volume to maintain the stable parameters this species rewards with full coloration and active hunting behavior. Lid fit is non-negotiable. Longnose Hawkfish are confirmed jumpers. They launch from a perch when startled -- by a sudden light change, a reflection, an aggressive tankmate, or simple curiosity -- and a fish found on the floor is almost never recoverable. A tight-fitting mesh lid or solid glass lid with no gaps larger than half an inch is mandatory on any tank housing this species. ### Flow and Filtration: Mimicking Deep Reef Slopes Aim for moderate to strong flow with good surface agitation and thorough oxygenation. This species originates from current-swept outer reef faces, and it handles significant water movement comfortably. A protein skimmer is strongly recommended -- both for water quality and for the dissolved oxygen contribution. Avoid dead spots in the rockwork where debris accumulates; the Longnose Hawkfish picks perching sites at multiple heights and will use well-circulated rockwork extensively. ## Diet & Feeding ### High-Protein Carnivorous Needs Longnose Hawkfish are obligate carnivores with a strong preference for crustaceans in the wild. In captivity, build the diet around frozen meaty foods: mysis shrimp, vitamin-enriched brine shrimp, finely chopped krill, and occasional silversides or clam. Variety maintains both health and the vivid red pigmentation. Color-enhancing frozen foods containing carotenoids help preserve the red crosshatch pattern. The long snout gives the fish a mechanical advantage when picking food off the substrate or out of crevices in the rockwork. Target feeding with a turkey baster or feeding stick placed near a favorite perch gets food to the fish without being outcompeted by faster tankmates. ### Training to Accept Prepared Pellets and Flakes Most Longnose Hawkfish transition to high-quality marine pellets within one to two weeks of arrival. Introduce pellets immediately after a frozen food feeding when the fish is already in active feeding mode. Repeat for several sessions and the fish will learn to treat pellets as food. A pellet-trained hawkfish is significantly easier to manage long-term and to medicate when needed. ### Feeding Frequency for Active Hunters Feed once or twice daily in small portions that are consumed within two to three minutes. A consistently well-fed Longnose Hawkfish is less inclined to hunt invertebrate tankmates and maintains more stable territorial behavior toward other fish. Do not allow this species to go more than two days without food -- hunger escalates predatory behavior noticeably. ## Tank Mates & Compatibility > **NOT reef-safe with shrimp or small ornamentals** > > Longnose Hawkfish will eat small ornamental shrimp. Sexy shrimp, peppermint shrimp, anemone shrimp, and most small ornamental crustaceans are at high risk. Large cleaner shrimp like Skunk Cleaners have better odds, but there are no guarantees as the hawkfish grows. If your reef plan relies on a shrimp-based cleanup crew, this is not the right centerpiece fish. ### The "Reef Safe" Debate: Shrimp and Small Crustaceans The Longnose Hawkfish is reef safe in the strictest coral sense -- it does not nip at polyps, does not eat coral tissue, and coexists peacefully with LPS and SPS colonies. The caveat is everything else small enough to eat. The elongated snout is precision equipment for extracting crustaceans from hiding spots, and an ornamental shrimp in the same tank is a matter of when, not if. Some hobbyists report success keeping larger Skunk Cleaner Shrimp by adding the hawkfish last while the shrimp is already established and large, but this is not a reliable strategy over the fish's lifetime. Hermit crabs in small shells are also at risk. Larger hermits in substantial shells tend to be left alone. Snails are generally ignored. ### Best Community Partners The Longnose Hawkfish fits best with semi-aggressive to moderately aggressive saltwater fish that can hold their own without triggering direct conflict. Good options include tangs (yellow tang, tomini tang, scopas tang), dwarf angelfish, larger wrasses, clownfish, and larger blennies. The [royal gramma](/species/royal-gramma) makes a good peaceful companion provided both fish have distinct territories in the rockwork. Avoid extremely small or shy fish the hawkfish may harass and avoid other hawkfish species (see below). Refer to the [saltwater aquarium setup guide](/guides/saltwater-aquarium) for general tank planning advice when building a semi-aggressive community. ### Dealing with Conspecific Aggression: Keeping Singles vs. Pairs > **Single specimen -- extreme aggression to other hawkfish** > > Do not attempt to keep two Longnose Hawkfish together unless you have purchased a verified mated pair from a reputable source. Two adults in the same system will fight relentlessly, and in tanks under 100 gallons the outcome is almost always fatal for the loser. This aggression extends to other hawkfish species -- they view the entire Cirrhitidae family as direct competition. One hawkfish per system is the standard rule. In the wild, Longnose Hawkfish are occasionally found in male-female pairs, with the male being smaller. Verified mated pairs from specialty marine vendors do coexist in aquariums, but sourcing a genuine pair is expensive and not straightforward. The default recommendation for home aquariums is a single specimen. ## Common Health Issues ### Identifying Marine Ich and Velvet Longnose Hawkfish are susceptible to the same parasites that affect other reef fish. Marine ich (*Cryptocaryon irritans*) presents as white spots on the body and fins. Marine velvet (*Amyloodinium ocellatum*) produces a finer, gold-dust coating and progresses faster. Both require copper-based treatment in a quarantine tank -- never in a display reef, where copper kills invertebrates and binds permanently to live rock and substrate. Because this species originates from deeper water and is often wild-caught rather than captive-bred, decompression stress during collection and shipping is an additional health concern. See the section below. ### Decompression Issues in Wild-Caught Specimens Wild Longnose Hawkfish collected from depth can arrive with internal decompression injuries if they were not brought up slowly. Signs include buoyancy problems, listless floating, or an inability to stay perched. Mild cases sometimes resolve over days to weeks in a quiet, stable quarantine environment. Severe cases rarely recover fully. When sourcing, prefer vendors that work with importers known for careful decompression handling, or ask about the collection depth and shipping protocol. ### Quarantine Protocols Quarantine every Longnose Hawkfish for two to four weeks in a bare-bottom tank with PVC fittings or artificial perches before adding to the display reef. Observe for disease symptoms, confirm the fish is eating, and run prophylactic copper treatment at therapeutic levels if your quarantine protocol includes it. The quarantine period also allows decompression-related issues to manifest and begin resolving before the fish enters a system with live invertebrates. ## Where to Buy & What to Look For ### The LFS Inspection Checklist: Focus on the Snout The Longnose Hawkfish has a specific vulnerability at purchase time that other species do not share: its snout. The elongated mouth structure is fragile relative to the body and is frequently abraded or bruised during shipping when fish are not packed with adequate separation. Rubbing injuries on the snout tip or along the jaw line can develop into chronic bacterial infections that are very difficult to resolve once established. When inspecting a Longnose Hawkfish at a local fish store, look closely at the snout tip and both sides of the jaw. Any redness, swelling, open lesion, or white discoloration in that area is a disqualifying defect. A clean, intact snout with natural coloration throughout is the single most important physical check for this species. Beyond the snout: ### Longnose Hawkfish Inspection Checklist - [ ] Snout tip and jaw are intact -- no redness, lesions, abrasion, or swelling - [ ] Active perching behavior -- fish should be sitting alert on a high spot, not lying flat - [ ] Eyes track movement as you approach the tank - [ ] Bold, vivid red crosshatch pattern with no fading or gray patches - [ ] Eating readily -- ask the store to feed the fish while you watch - [ ] No visible white spots, film, or gold-dust coating on the body - [ ] Fins intact with no fraying or torn edges - [ ] Tank water is clean with no dead fish visible in the same system ### Assessing Alertness and Perching Behavior In-Store A healthy Longnose Hawkfish will be perched on a rock or decoration at a high point in the display tank, watching the room. It should turn its head when you move in front of the glass and should show an immediate feeding response when food hits the water. A fish lying on the substrate, hiding behind equipment, or drifting listlessly near the surface is not a healthy purchase regardless of how attractive its coloration appears. ### Online vs. Local Fish Store Local fish stores offer a meaningful advantage for this species specifically. The snout is fragile in transit, and buying in person lets you inspect it directly before money changes hands. A fish that has already acclimated in a store tank has also survived the highest-risk phase of the supply chain. For the [saltwater fish overview](/guides/saltwater-fish) and general compatibility planning, an LFS with knowledgeable marine staff is also your best resource for confirming the species fits your existing community. > **Buy Local** > > Buy your Longnose Hawkfish in person whenever possible. The snout is this species' most common shipping injury site, and no product photo will show you early-stage abrasion damage. A local fish store lets you check the jaw line directly, watch the fish eat, and confirm its perching behavior before you commit. ## Quick-Reference Cheat Sheet ### Longnose Hawkfish Care At-a-Glance **Scientific name:** *Oxycirrhites typus* **Adult size:** Up to 5 inches (13 cm) **Tank size:** 75 gallons minimum; larger tanks provide better stability and perching options **Water parameters:** 72-78 degrees F, SG 1.023-1.025, pH 8.1-8.4, dKH 8-12, ammonia/nitrite 0 ppm, nitrate under 20 ppm **Flow:** Moderate to strong with good surface agitation -- originates from current-swept outer reef slopes **Diet:** Carnivore -- frozen mysis, brine, krill, chopped silversides; transitions to high-quality marine pellets **Feeding frequency:** 1-2 small meals per day **Reef safe?** With corals, yes.

Yes, with a caveat. They do not eat corals, but they are notorious for eating small ornamental shrimp like Sexy Shrimp or small Peppermints. Larger cleaners are usually safe, but caution is required. ### Do Longnose Hawkfish need a lid? Absolutely. They are darting fish and are among the most common species to jump out of open-top aquariums when startled or during nighttime hunting. ### Can I keep two Longnose Hawkfish together? Generally, no. They are territorial toward their own kind unless you purchase a verified mated pair. In most home aquaria under 100 gallons, keep only one. ### Why is my Hawkfish sitting on my corals? This is natural behavior. Because they lack a swim bladder, they perch rather than swim. They prefer high-vantage points like gorgonians or leather corals to watch for food. ### What is the minimum tank size for a Longnose Hawkfish? While they are small, they are active hunters. A 75-gallon tank is the recommended minimum, as it provides adequate territory, perching sites, and the water volume needed for stable parameters. --- *Source: [FishStores.org](https://www.fishstores.org/species/longnose-hawkfish)* *Last updated: April 24, 2026*
