{"product_id":"kleins-butterflyfish","title":"Klein's Butterflyfish","description":"\u003cp\u003eKlein’s Butterflyfish, \u003cem\u003eChaetodon kleinii\u003c\/em\u003e, is an attractive and adaptable saltwater fish known for its warm yellow to golden-brown coloration, pale vertical bands, and bold dark stripe running through the eye. Fine spotted or broken horizontal markings decorate the sides, while subtle blue coloration may develop around the upper head. Its deep, laterally compressed body and graceful swimming style give it the classic appearance associated with marine butterflyfish.\u003c\/p\u003e\n\u003cp\u003eNative to a remarkably broad range spanning the Red Sea and East Africa across the Indo-Pacific to Hawaii and Samoa, with populations also occurring around the Galápagos Islands, this species inhabits deeper lagoons, channels, and seaward reefs. Adults are commonly found alone or in pairs and browse reef environments for soft coral polyps, algae, zooplankton, and other available foods.\u003c\/p\u003e\n\u003cp\u003eReaching approximately 6 inches as an adult, Klein’s Butterflyfish is a relatively manageable butterflyfish for a mature marine aquarium. Its generally peaceful temperament, willingness to accept a varied captive diet, and active personality make it an appealing addition to fish-only and fish-only-with-live-rock aquariums. Because coral tissue forms a significant part of its natural diet, however, it should not be considered reliably safe for a reef aquarium.\u003c\/p\u003e\n\u003ch2\u003eQuick Care Guide\u003c\/h2\u003e\n\u003cp\u003eCare Level: Easy to Moderate\u003cbr\u003eMinimum Tank Size: 75 gallons\u003cbr\u003eTemperament: Peaceful\u003cbr\u003eDiet: Omnivore\u003cbr\u003eReef Safe: No\u003cbr\u003eRegion: Red Sea, Indo-Pacific, Hawaii, and Galápagos Islands\u003cbr\u003eScientific Name: \u003cem\u003eChaetodon kleinii\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eTank Requirements\u003c\/h2\u003e\n\u003cp\u003eProvide a mature marine aquarium with established live rock, sheltered caves, and plenty of open swimming room. Klein’s Butterflyfish is an active cruiser that benefits from being able to move freely around and between rock structures while investigating surfaces for food.\u003c\/p\u003e\n\u003cp\u003eArrange the aquascape to provide several secure retreats without overcrowding the aquarium. Established rockwork is particularly beneficial because it offers natural browsing opportunities and can help newly introduced specimens acclimate more comfortably.\u003c\/p\u003e\n\u003cp\u003eModerate water movement, good oxygenation, efficient filtration, and stable water quality are recommended. Although this species is generally considered one of the more adaptable butterflyfish, it should still be introduced to a well-established saltwater aquarium rather than an unstable or newly cycled system.\u003c\/p\u003e\n\u003cp\u003eA secure aquarium cover is advisable, particularly during initial acclimation when a startled fish may make sudden movements toward the surface.\u003c\/p\u003e\n\u003ch2\u003eDiet and Feeding\u003c\/h2\u003e\n\u003cp\u003eKlein’s Butterflyfish is an omnivorous reef browser that naturally consumes soft coral polyps, algae, zooplankton, and other small reef-associated foods.\u003c\/p\u003e\n\u003cp\u003eIn captivity, offer a varied diet including mysis shrimp, enriched brine shrimp, finely chopped shrimp, clam, mussel, krill, and quality frozen marine blends. Plankton-based preparations and foods formulated specifically for butterflyfish can also provide excellent nutritional variety.\u003c\/p\u003e\n\u003cp\u003eSupplement meaty foods with spirulina-based preparations, marine algae, and high-quality omnivore pellets once the fish is readily accepting prepared foods. Newly introduced specimens may respond particularly well to frozen mysis or clam and mussel presented near established rockwork.\u003c\/p\u003e\n\u003cp\u003eFeed two to three smaller meals per day when practical to support good body condition and complement its natural grazing and browsing behavior.\u003c\/p\u003e\n\u003ch2\u003eTemperament and Tankmates\u003c\/h2\u003e\n\u003cp\u003eKlein’s Butterflyfish is generally peaceful toward unrelated marine fish and works well in many appropriately sized community aquariums. Suitable tankmates include tangs, rabbitfish, peaceful wrasses, clownfish, gobies, cardinalfish, and compatible angelfish.\u003c\/p\u003e\n\u003cp\u003eTerritorial behavior can occur toward other butterflyfish, particularly similar species competing for the same feeding areas. A single specimen is the simplest arrangement for most aquariums.\u003c\/p\u003e\n\u003cp\u003eAdults naturally occur singly or in pairs. An established compatible pair may be maintained in a sufficiently spacious aquarium, but two unrelated specimens should not automatically be expected to pair successfully.\u003c\/p\u003e\n\u003cp\u003eAvoid overly aggressive tankmates that may continually harass the butterflyfish or prevent it from feeding.\u003c\/p\u003e\n\u003ch2\u003eReef Compatibility\u003c\/h2\u003e\n\u003cp\u003eKlein’s Butterflyfish is not considered reef safe. Soft coral polyps form an important part of its natural diet, and captive specimens may actively nip at or consume desirable coral tissue.\u003c\/p\u003e\n\u003cp\u003eSoft corals are particularly vulnerable, but stony corals, zoanthids, anemones, tubeworms, and other sessile invertebrates may also be investigated. Individual feeding preferences vary, but regular feeding does not guarantee that a specimen will ignore corals.\u003c\/p\u003e\n\u003cp\u003eFor predictable long-term care, a fish-only or fish-only-with-live-rock aquarium is the preferred 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, excellent 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 Soft corals and other sessile invertebrates may be nipped or consumed.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMature rockwork is beneficial:\u003c\/strong\u003e Established surfaces provide natural browsing opportunities and shelter during acclimation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eVaried diet:\u003c\/strong\u003e Offer both marine-based animal foods and algae-rich preparations for balanced nutrition.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eButterflyfish compatibility:\u003c\/strong\u003e Territorial behavior may occur toward other butterflyfish, especially similar species.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eFrequent feeding:\u003c\/strong\u003e Two to three smaller meals per day help maintain body condition and support natural browsing behavior.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TSA Fish","offers":[{"title":"S","offer_id":52451763487018,"sku":"BUTTERxKleinS","price":50.99,"currency_code":"USD","in_stock":false},{"title":"SM","offer_id":52451763519786,"sku":"BUTTERxKleinSM","price":56.99,"currency_code":"USD","in_stock":true},{"title":"M","offer_id":52451763552554,"sku":"BUTTERxKleinM","price":71.99,"currency_code":"USD","in_stock":true},{"title":"ML","offer_id":52451763585322,"sku":"BUTTERxKleinML","price":86.99,"currency_code":"USD","in_stock":true},{"title":"L","offer_id":52451763618090,"sku":"BUTTERxKleinL","price":110.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/0873\/7322\/files\/KleinButterfly_96bcdf57-f917-442f-912b-81795ec9925f.png?v=1788294450","url":"https:\/\/topshelfaquatics.com\/products\/kleins-butterflyfish","provider":"Top Shelf Aquatics ","version":"1.0","type":"link"}
