Its cream-to-tan body is marked with dramatic black bands, vivid blue facial lines, yellow-orange accents, and abstract geometric patterns that give the species its familiar Picasso name. As it matures, its confident swimming style and unmistakable personality make it an impressive centerpiece marine aquarium fish.\u003c\/p\u003e\n\u003cp\u003eNative to shallow reef flats and protected lagoons across a broad portion of the Indo-Pacific, \u003cem\u003eRhinecanthus aculeatus\u003c\/em\u003enaturally patrols areas of rock, rubble, and sand in search of food. It is an intelligent, territorial triggerfish that becomes increasingly assertive with age. Because it feeds readily on crustaceans, mollusks, and other reef animals, it is best suited to a spacious fish-only aquarium or FOWLR system rather than a traditional reef aquarium.\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 Aggressive\u003cbr\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e Carnivore\u003cbr\u003e\u003cstrong\u003eReef Safe:\u003c\/strong\u003e No\u003cbr\u003e\u003cstrong\u003eRegion:\u003c\/strong\u003e Indo-Pacific, from East Africa eastward through the central Pacific to Hawaii and French Polynesia, north to southern Japan and south to northern Australia\u003cbr\u003e\u003cstrong\u003eScientific Name:\u003c\/strong\u003e \u003cem\u003eRhinecanthus aculeatus\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eTank Requirements\u003c\/h2\u003e\n\u003cp\u003eProvide a spacious aquarium with a combination of substantial open swimming room and sturdy rockwork. Caves and crevices are important because this triggerfish will often retreat into rockwork and use its locking dorsal spine to secure itself when resting or threatened.\u003c\/p\u003e\n\u003cp\u003eAll rock structures should be stable and securely positioned. Humu Picasso Triggerfish are strong, inquisitive fish that may move loose rubble, shells, or smaller pieces of aquascaping while investigating their surroundings. A sand or coarse-sand substrate works well and allows natural foraging behavior.\u003c\/p\u003e\n\u003cp\u003eStrong biological filtration and efficient mechanical filtration are recommended because triggerfish are enthusiastic feeders that can produce a significant nutrient load. Moderate to strong water movement is appropriate as long as quieter areas remain available around caves and resting locations. A secure aquarium cover is also recommended.\u003c\/p\u003e\n\u003ch2\u003eDiet and Feeding\u003c\/h2\u003e\n\u003cp\u003eIn the wild, this species consumes a broad range of benthic foods, including crustaceans, mollusks, worms, sea urchins, and other small animals. Captive specimens generally adapt readily to a varied diet of high-quality meaty marine foods.\u003c\/p\u003e\n\u003cp\u003eOffer foods such as mysis shrimp, krill, chopped shrimp, squid, clam, mussel, scallop, and quality marine carnivore pellets. Larger specimens benefit from occasional shell-on shrimp, clam, or other appropriately sized hard foods that encourage natural chewing and help maintain the teeth.\u003c\/p\u003e\n\u003cp\u003eFeed one to two appropriately sized meals per day, varying the menu rather than relying heavily on a single food.\u003c\/p\u003e\n\u003ch2\u003eTemperament and Tankmates\u003c\/h2\u003e\n\u003cp\u003eHumu Picasso Triggerfish are territorial and can become considerably more aggressive as they mature. They are generally best housed as a single specimen unless the aquarium is exceptionally large and compatibility is carefully planned.\u003c\/p\u003e\n\u003cp\u003eChoose robust tankmates of similar size that are capable of holding their own without being overly aggressive themselves. Larger tangs, certain angelfish, sturdy wrasses, and other substantial fish may be appropriate depending on aquarium size and individual temperament.\u003c\/p\u003e\n\u003cp\u003eAvoid very small fish, slow or timid species, and fish with long delicate fins. Other triggerfish and similarly shaped territorial fish should be added only with considerable caution. Introducing the Picasso Triggerfish after more peaceful tankmates are established can sometimes help reduce territorial dominance.\u003c\/p\u003e\n\u003ch2\u003eReef Compatibility\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eNot reef safe.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhile the fish may not constantly target every coral, its natural feeding behavior makes it unsuitable for a conventional reef aquarium.
