Also known as the Bluespot Butterflyfish, Blueblotch Butterflyfish or Blue-dash Butterflyfish, it inhabits shallow coral-rich lagoons, coastal reefs and outer reef slopes. Adults are highly specialised coral feeders that rely heavily on living coral polyps, particularly Pocillopora species. Although exceptionally attractive, its specialised natural diet and poor adaptability to conventional aquarium foods make it suitable only for expert fishkeepers with appropriate specialist facilities.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eCommon Name:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eBlue Spot Butterflyfish, Bluespot Butterflyfish, Blueblotch Butterflyfish, Blue-blotched Butterflyfish, Blue-dash Butterflyfish, Coral Butterflyfish.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eScientific Name (Latin):\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eChaetodon plebeius\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eMaximum Size:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eApproximately 15 cm in total length when fully grown.\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\u003eWestern Pacific, from the Andaman Sea and Southeast Asia eastwards to Fiji, north to southern Japan and south to Australia, including the Great Barrier Reef, Coral Sea reefs and Lord Howe Island.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eBlue Spot Butterflyfish inhabit shallow coastal reefs, protected lagoons and outer reef slopes at depths of approximately 1–14 metres.
