{"product_id":"masked-rabbit-fish-siganus-puellus","title":"Masked Rabbitfish","description":"\u003cp\u003eThe Masked Rabbitfish is a striking saltwater fish with a vivid yellow-to-orange body covered in fine blue lines and spots. A broad black band crossing the eye creates its distinctive “masked” appearance, while bright yellow fins complete its bold coloration. Reaching up to approximately 15 inches, this active marine aquarium fish becomes an impressive centerpiece for a large reef or fish-only aquarium. \u003c\/p\u003e\n\u003cp\u003eNative to the Indo-West Pacific, \u003cem\u003eSiganus puellus\u003c\/em\u003e inhabits clear, coral-rich lagoons, outer reef flats, and seaward reefs at depths of approximately 1–30 meters. Its distribution extends from the Cocos-Keeling Islands and South China Sea east to the Gilbert Islands, north to the Ryukyu Islands, and south to New Caledonia and the southern Great Barrier Reef. Juveniles may gather in schools around shallow \u003cem\u003eAcropora\u003c\/em\u003e-dominated reefs, while adults are commonly encountered in pairs. \u003c\/p\u003e\n\u003cp\u003eAlthough generally peaceful and adaptable, the Masked Rabbitfish requires substantial swimming room, frequent feeding, and careful consideration in a reef aquarium. Adults consume algae as well as sponges and tunicates, making this attractive rabbitfish reef safe only with caution. Its stout dorsal, anal, and pelvic spines are venomous and can inflict a painful sting. \u003c\/p\u003e\n\u003ch2\u003eQuick Care Guide\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCare Level:\u003c\/strong\u003e Moderate\u003cbr\u003e\u003cstrong\u003eMinimum Tank Size:\u003c\/strong\u003e 180 gallons\u003cbr\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e Peaceful\u003cbr\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e Omnivore \/ Algae and Sponge Browser\u003cbr\u003e\u003cstrong\u003eReef Safe:\u003c\/strong\u003e With Caution\u003cbr\u003e\u003cstrong\u003eRegion:\u003c\/strong\u003e Indo-West Pacific\u003cbr\u003e\u003cstrong\u003eScientific Name:\u003c\/strong\u003e \u003cem\u003eSiganus puellus\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eTank Requirements\u003c\/h2\u003e\n\u003cp\u003eProvide a large, mature aquarium with broad open swimming lanes and substantial rockwork arranged around the sides and rear of the tank. The rockwork should offer caves for nighttime shelter, shaded retreats, and established surfaces where the fish can browse naturally. Keep all structures stable, as a full-grown rabbitfish is a powerful and active swimmer.\u003c\/p\u003e\n\u003cp\u003eA long aquarium is preferable to a tall, narrow system. Moderate to strong, well-distributed water movement, efficient protein skimming, good oxygenation, and dependable biological filtration are recommended. Frequent feeding and the fish’s large adult size can place a considerable demand on water quality.\u003c\/p\u003e\n\u003cp\u003eA secure lid is advisable because rabbitfish may jump when startled. Leave adequate space between the rockwork and aquarium panels so the fish can turn comfortably without contacting its venomous spines. Use extra care during capture, transfer, and aquarium maintenance; never handle this species with bare hands. Its 180-gallon minimum reflects its potential 15-inch adult size and active swimming behavior. \u003c\/p\u003e\n\u003ch2\u003eDiet and Feeding\u003c\/h2\u003e\n\u003cp\u003eThe Masked Rabbitfish is an omnivorous browser rather than a strict herbivore. Juveniles consume filamentous algae, while adults naturally feed on algae, tunicates, and sponges.

New arrivals may initially respond best to live macroalgae, enriched brine shrimp, or food placed close to their preferred shelter. A varied diet containing both marine vegetable matter and suitable animal-based foods is more appropriate than feeding algae alone. \u003c\/p\u003e\n\u003ch2\u003eTemperament and Tankmates\u003c\/h2\u003e\n\u003cp\u003eThe Masked Rabbitfish is generally peaceful toward unrelated marine fish and can coexist with many medium-to-large community species. Suitable tankmates include tangs, larger angelfish, peaceful wrasses, butterflyfish, anthias, clownfish, and other fish too large to be intimidated or accidentally injured.\u003c\/p\u003e\n\u003cp\u003eIt may become territorial toward other rabbitfish, foxfaces, or herbivorous fish competing for the same grazing areas. Keeping a single specimen is the safest choice unless an established compatible pair is available. Adults naturally occur in pairs, but randomly combining two individuals does not guarantee compatibility. \u003c\/p\u003e\n\u003cp\u003eAvoid highly aggressive fish that may repeatedly harass it. When frightened, rabbitfish can erect their venomous spines in defense, potentially injuring both the aggressor and the aquarist attempting to intervene.\u003c\/p\u003e\n\u003ch2\u003eReef Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe Masked Rabbitfish is \u003cstrong\u003ereef safe with caution\u003c\/strong\u003e. It may coexist successfully with corals when well fed, but its natural diet makes it less predictable than primarily algae-eating rabbitfish. Sponges and tunicates are at particular risk, and some individuals may also nip soft corals, fleshy LPS corals, zoanthids, or clam mantles. \u003c\/p\u003e\n\u003cp\u003eOrnamental shrimp, crabs, and snails are generally not primary prey, but small or exposed invertebrates cannot be guaranteed safe. Maintaining regular feedings and providing marine algae may reduce opportunistic picking, but it will not eliminate the species’ natural interest in sessile invertebrates.\u003c\/p\u003e\n\u003cp\u003eA fish-only aquarium with live rock provides the most predictable environment. In a reef aquarium, monitor corals, clams, sponges, and tunicates for repeated nipping or unexplained tissue retraction.\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 strong oxygenation and undetectable ammonia and nitrite.
