{"product_id":"double-saddle-butterflyfish-chaetodon-ulietensis","title":"Double Saddle Butterflyfish","description":"\u003cp\u003eThe Double Saddle Butterflyfish, \u003cem\u003eChaetodon ulietensis\u003c\/em\u003e, is a beautifully patterned saltwater fish distinguished by its pearly white body, fine vertical gray-black lines, and two prominent dark saddle-shaped markings across the upper body. A bold black eye band contrasts with the bright yellow posterior body and fins, while a dark marking near the caudal peduncle completes its unmistakable appearance. It is also commonly known as the Pacific Double-Saddle Butterflyfish or False Falcula Butterflyfish.\u003c\/p\u003e\n\u003cp\u003eNative to the Indo-Pacific, this species inhabits coral-rich lagoon reefs and, less commonly, seaward reef environments. Adults are typically encountered singly, in pairs, or in small groups as they browse reef structure for plant and animal foods. Its active but graceful swimming style and bold contrasting coloration make it an attractive display fish.\u003c\/p\u003e\n\u003cp\u003eReaching approximately 6 inches as an adult, the Double Saddle Butterflyfish is well suited to a spacious fish-only or fish-only-with-live-rock aquarium. It is considered one of the more adaptable butterflyfish once established, but its natural feeding behavior includes corals and other sessile invertebrates, making it unsuitable for most traditional reef aquariums.\u003c\/p\u003e\n\u003ch2\u003eQuick Care Guide\u003c\/h2\u003e\n\u003cp\u003eCare Level: Moderate\u003cbr\u003eMinimum Tank Size: 120 gallons\u003cbr\u003eTemperament: Peaceful\u003cbr\u003eDiet: Omnivore\u003cbr\u003eReef Safe: No\u003cbr\u003eRegion: Indo-Pacific\u003cbr\u003eScientific Name: \u003cem\u003eChaetodon ulietensis\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eTank Requirements\u003c\/h2\u003e\n\u003cp\u003eProvide a mature marine aquarium with substantial rockwork, caves, and sheltered passages along with generous open swimming space. Although relatively modest in adult length, the Double Saddle Butterflyfish is an active cruiser and benefits from a long aquarium with room to move comfortably throughout the display.\u003c\/p\u003e\n\u003cp\u003eEstablished live rock provides valuable shelter and natural browsing surfaces. Arrange the aquascape so the fish can investigate rockwork without being confined by narrow passages or excessively dense coral structures.\u003c\/p\u003e\n\u003cp\u003eModerate water movement, good oxygenation, efficient filtration, and stable water quality are recommended. A secure aquarium cover is also advisable, particularly during acclimation when newly introduced butterflyfish may make sudden movements if startled.\u003c\/p\u003e\n\u003ch2\u003eDiet and Feeding\u003c\/h2\u003e\n\u003cp\u003eThe Double Saddle Butterflyfish is an omnivorous reef browser that naturally consumes both plant and animal material, including algae and a variety of small benthic invertebrates. Coral polyps, anemones, worms, and other sessile organisms may also be investigated as food.\u003c\/p\u003e\n\u003cp\u003eIn captivity, offer mysis shrimp, enriched brine shrimp, finely chopped shrimp, clam, mussel, krill, and quality frozen marine blends. Butterflyfish preparations containing marine invertebrate ingredients can provide additional variety.\u003c\/p\u003e\n\u003cp\u003eSpirulina-based foods, marine algae preparations, and high-quality omnivore pellets can also be incorporated once the fish is feeding confidently. Feed two to three smaller meals per day when practical.\u003c\/p\u003e\n\u003ch2\u003eTemperament and Tankmates\u003c\/h2\u003e\n\u003cp\u003eThe Double Saddle Butterflyfish is generally peaceful toward unrelated marine fish and works well with many appropriately sized community species. Suitable tankmates include tangs, rabbitfish, peaceful wrasses, clownfish, larger gobies, and compatible angelfish.\u003c\/p\u003e\n\u003cp\u003eAdults naturally occur alone, in pairs, or in small groups. A compatible pair may be maintained in a sufficiently spacious aquarium, although two unrelated specimens should not automatically be expected to pair successfully.\u003c\/p\u003e\n\u003cp\u003eUse caution with other butterflyfish, particularly similar-looking species, as territorial behavior may occur. Avoid highly aggressive tankmates that could intimidate the fish or interfere with feeding.\u003c\/p\u003e\n\u003ch2\u003eReef Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe Double Saddle Butterflyfish is not considered reef safe. Its natural feeding behavior includes coral polyps and other sessile invertebrates, and captive specimens may nip or consume stony corals, soft corals, mushroom corals, zoanthids, anemones, and tubeworms.\u003c\/p\u003e\n\u003cp\u003eClam mantles and other exposed fleshy invertebrates may also be investigated. Frequent feeding does not guarantee that a specimen will ignore desirable reef organisms.\u003c\/p\u003e\n\u003cp\u003eA fish-only or fish-only-with-live-rock aquarium is the most dependable long-term environment.\u003c\/p\u003e\n\u003ch2\u003eWater Parameters\u003c\/h2\u003e\n\u003cp\u003eTemperature: 75–80°F\u003cbr\u003eSpecific Gravity: 1.024–1.026\u003cbr\u003epH: 8.1–8.4\u003cbr\u003eAlkalinity: 8–12 dKH\u003c\/p\u003e\n\u003cp\u003eStable salinity, good oxygenation, and consistently clean water are more important than attempting to maintain an exact value within these ranges.\u003c\/p\u003e\n\u003ch2\u003eCommon Considerations\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eNot reef safe:\u003c\/strong\u003e Corals, anemones, tubeworms, and other sessile invertebrates may be nipped or consumed.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMature aquarium preferred:\u003c\/strong\u003e Established rockwork provides shelter and natural browsing opportunities.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eVaried diet is important:\u003c\/strong\u003e Offer a combination of marine invertebrate foods, frozen preparations, and algae-based foods.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eButterflyfish compatibility:\u003c\/strong\u003e Use caution when combining it with other butterflyfish, particularly similar species.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eActive swimmer:\u003c\/strong\u003e Despite its moderate adult size, generous horizontal swimming space is important for long-term housing.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TSA Fish","offers":[{"title":"S","offer_id":52451921985834,"sku":"BUTTERxDoubleS","price":74.99,"currency_code":"USD","in_stock":false},{"title":"SM","offer_id":52451922018602,"sku":"BUTTERxDoubleSM","price":83.99,"currency_code":"USD","in_stock":false},{"title":"M","offer_id":52451922051370,"sku":"BUTTERxDoubleM","price":104.99,"currency_code":"USD","in_stock":false},{"title":"ML","offer_id":52451922084138,"sku":"BUTTERxDoubleML","price":134.99,"currency_code":"USD","in_stock":false},{"title":"L","offer_id":52451922116906,"sku":"BUTTERxDoubleL","price":164.99,"currency_code":"USD","in_stock":false},{"title":"XL","offer_id":52451922149674,"sku":"BUTTERxDoubleX","price":209.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/0873\/7322\/files\/DoubleSaddleButterfly_696ef0e0-2232-41aa-be0a-1a22eacaee48.png?v=1788291657","url":"https:\/\/topshelfaquatics.com\/products\/double-saddle-butterflyfish-chaetodon-ulietensis","provider":"Top Shelf Aquatics ","version":"1.0","type":"link"}
