{"product_id":"arc-eye-hawkfish","title":"Arc Eye Hawkfish","description":"\u003cp\u003eThe Arc Eye Hawkfish is a distinctive saltwater fish named for the vivid horseshoe-shaped marking that curves behind each eye. Its coloration varies from warm reddish brown to pale pink or tan, often with a broad white stripe along the rear half of the body. Bright orange markings on the gill covers and small tassels at the tips of the dorsal spines complete its highly detailed appearance. \u003c\/p\u003e\n\u003cp\u003eNative to the tropical Indo-Pacific, \u003cem\u003eParacirrhites arcatus\u003c\/em\u003e ranges from East Africa across the Pacific to Hawaii and the Pitcairn region, north to southern Japan and south to Australia. It inhabits coastal lagoons and seaward reefs, where it typically rests on branching corals and elevated reef structures while watching for prey. The species can reach approximately 8 inches in total length. \u003c\/p\u003e\n\u003cp\u003eIts alert expression, unusual perching behavior, and bold personality make the Arc Eye Hawkfish an engaging addition to a fish-only aquarium or carefully planned reef aquarium. It generally leaves healthy corals alone, but its natural diet includes shrimp, crabs, other crustaceans, and small fish. For this reason, it is best suited to aquariums with robust tankmates and without small ornamental invertebrates. \u003c\/p\u003e\n\u003ch2\u003eQuick Care Guide\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCare Level:\u003c\/strong\u003e Easy to Moderate\u003cbr\u003e\u003cstrong\u003eMinimum Tank Size:\u003c\/strong\u003e 75 gallons\u003cbr\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e Semi-aggressive\u003cbr\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e Carnivore\u003cbr\u003e\u003cstrong\u003eReef Safe:\u003c\/strong\u003e With Caution\u003cbr\u003e\u003cstrong\u003eRegion:\u003c\/strong\u003e Indo-Pacific\u003cbr\u003e\u003cstrong\u003eScientific Name:\u003c\/strong\u003e \u003cem\u003eParacirrhites arcatus\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eTank Requirements\u003c\/h2\u003e\n\u003cp\u003eProvide a mature aquarium with substantial live rock arranged into ledges, caves, overhangs, and elevated lookout points. The Arc Eye Hawkfish spends much of its time resting on rockwork or coral branches before making short, rapid movements to capture food or defend its territory. Stable perches throughout the aquarium encourage natural behavior and allow the fish to remain visible. \u003c\/p\u003e\n\u003cp\u003eLeave open swimming routes between the rock structures and provide a secure cave for nighttime shelter. A sand or fine-gravel substrate is suitable, although this species has no specialized substrate requirement. Moderate, well-distributed water movement and strong oxygenation are appropriate.\u003c\/p\u003e\n\u003cp\u003eUse a fitted lid or secure mesh cover, as hawkfish may jump when startled or during territorial disputes. Corals and rock structures should be securely mounted because a full-grown specimen may dislodge loose fragments while moving between perches. \u003c\/p\u003e\n\u003ch2\u003eDiet and Feeding\u003c\/h2\u003e\n\u003cp\u003eThe Arc Eye Hawkfish is a predatory carnivore that naturally feeds primarily on shrimp, crabs, other crustaceans, and small fish. Its typical hunting strategy involves remaining motionless on an elevated perch before darting rapidly toward passing prey. \u003c\/p\u003e\n\u003cp\u003eOffer a varied selection of mysis shrimp, enriched brine shrimp, chopped clam or mussel, krill, chopped shrimp, squid, and quality frozen marine carnivore blends. Appropriately sized sinking or slow-sinking pellets may also be accepted once the fish becomes established.\u003c\/p\u003e\n\u003cp\u003eFeed one or two small meals daily. Allow some food to drift near the fish’s preferred lookout points, particularly during acclimation. Live feeder fish are unnecessary and should not be required for a healthy captive diet.\u003c\/p\u003e\n\u003ch2\u003eTemperament and Tankmates\u003c\/h2\u003e\n\u003cp\u003eThis hawkfish is confident, territorial, and capable of becoming aggressive toward newly introduced fish. It may defend a favored cave or perch and is especially likely to challenge other hawkfish, similarly shaped bottom-dwelling species, or fish competing for the same territory. It is usually best maintained singly. \u003c\/p\u003e\n\u003cp\u003eSuitable tankmates include tangs, rabbitfish, medium-sized angelfish, larger clownfish, robust wrasses, butterflyfish, and other marine fish too large to be swallowed. Avoid timid species that may be intimidated or repeatedly displaced from feeding areas.\u003c\/p\u003e\n\u003cp\u003eVery small gobies, juvenile fish, ornamental shrimp, and small crabs may be hunted. Introduce peaceful or shy fish before the hawkfish whenever possible, and monitor all new additions for territorial chasing.\u003c\/p\u003e\n\u003ch2\u003eReef Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe Arc Eye Hawkfish is \u003cstrong\u003ereef safe with caution\u003c\/strong\u003e. It does not normally consume healthy stony corals, soft corals, zoanthids, or clams. The primary reef concern is predation on mobile animals rather than direct coral feeding. \u003c\/p\u003e\n\u003cp\u003eCleaner shrimp, peppermint shrimp, small crabs, and other ornamental crustaceans may be eaten, particularly when they are small enough to fit in the fish’s mouth. Tiny fish are also at risk. Larger established shrimp may occasionally coexist with an individual hawkfish, but they should not be considered reliably safe.\u003c\/p\u003e\n\u003cp\u003eFrequent perching on coral colonies is normal. Although it usually causes no lasting damage, the fish may irritate delicate corals or shift unsecured fragments as it moves between lookout points.\u003c\/p\u003e\n\u003ch2\u003eWater Parameters\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eTemperature:\u003c\/strong\u003e 75–80°F\u003cbr\u003e\u003cstrong\u003eSpecific Gravity:\u003c\/strong\u003e 1.024–1.026\u003cbr\u003e\u003cstrong\u003epH:\u003c\/strong\u003e 8.1–8.4\u003cbr\u003e\u003cstrong\u003eAlkalinity:\u003c\/strong\u003e 8–12 dKH\u003c\/p\u003e\n\u003cp\u003eMaintain consistent salinity, good oxygenation, and low levels of accumulated waste.
