Unlike many larger angelfish, Genicanthus species are primarily open-water planktivores rather than coral grazers, making them one of the more dependable choices for reef aquariums. Peaceful, active and highly attractive, this species is best suited to spacious, mature marine systems with excellent water quality and plenty of open swimming room.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eCommon Name:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eMasked Swallowtail Angel, Japanese Swallowtail Angelfish\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eScientific Name (Latin):\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eGenicanthus semifasciatus\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003e\u003cstrong\u003eMaximum Size\u003c\/strong\u003e:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eApproximately 20–22 cm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eWater Type:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eMarine\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eOrigin \/ Natural Habitat:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eThe Masked Swallowtail Angel is associated with deeper reef slopes and offshore reef environments in the western Pacific.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eIt typically inhabits open water close to reef structure, where it feeds on plankton while remaining near caves and overhangs for shelter.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eWater Parameters:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eTemperature: 24–26°C\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003epH Range: 8.1–8.4\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eSalinity: SG 1.024–1.026\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eNitrate: Low and stable\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eAmmonia\/Nitrite: 0 ppm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003ePeaceful to Semi-Aggressive\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe Masked Swallowtail Angel is generally peaceful towards unrelated marine fish and is considerably less territorial than many other angelfish.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eMales may become competitive towards other Genicanthus males, particularly in smaller aquariums, while females are usually more tolerant.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eOmnivore \/ Planktivore\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe Masked Swallowtail Angel naturally feeds largely on planktonic foods within the water column.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eIn the aquarium, offer a varied diet including frozen mysis, enriched brine shrimp, finely chopped krill, marine pellets, flakes and quality angelfish foods.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eSmall amounts of algae-based and spirulina-enriched foods can also be included regularly.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eMinimum Tank Size:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eApproximately 450 litres\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eIts active open-water swimming behaviour means the Masked Swallowtail Angel requires substantial horizontal swimming space.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eBehaviour \u0026amp;
