Also known as the Blackpatch Triggerfish or Bursa Triggerfish, it naturally inhabits shallow coral reefs, lagoons and rubble-strewn coastal habitats. This intelligent, highly active triggerfish develops a confident personality and powerful feeding response, but its territorial behaviour, strong teeth and appetite for invertebrates make it best suited to a spacious fish-only or FOWLR aquarium with robust tank mates.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eCommon Name:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eBlackbelly Triggerfish, Black Belly Triggerfish, Blackpatch Triggerfish, Black-patch Triggerfish, Bursa Triggerfish.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eScientific Name (Latin):\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eRhinecanthus verrucosus\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eMaximum Size:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eCapable of reaching approximately 23 cm when fully grown.
