Also known as the Eastern Triangular Butterflyfish or Baroness Butterflyfish, this species is best suited to expert marine keepers only. In the wild it feeds almost exclusively on Acropora coral polyps, which makes it very difficult to maintain long-term in captivity unless it is already feeding well and specialist care can be provided.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Name:\u003c\/strong\u003e\u003cbr\u003eEastern Triangle Butterflyfish.

In the wild it is associated with lagoon reefs, seaward reefs and coral-rich reef slopes, usually living in pairs and defending feeding territories.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWater Parameters:\u003c\/strong\u003e\u003cbr\u003eTemperature: 24–27°C\u003cbr\u003epH Range: 8.1–8.4\u003cbr\u003eSalinity: 1.020–1.025 SG\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e\u003cbr\u003eGenerally peaceful to semi-aggressive, but territorial towards similar butterflyfish and competitors, especially in smaller aquariums. It is not an aggressive predator, but its specialist feeding behaviour makes it unsuitable for most standard mixed reef communities.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e\u003cbr\u003eHighly specialist corallivore. In the wild it feeds almost exclusively on Acropora coral polyps. In captivity, some individuals may accept finely chopped clam, mussel, prawn, mysis, brineshrimp, specialist frozen marine blends or food presented on coral skeletons, but many specimens are difficult to convert to prepared foods. Only purchase if feeding has been confirmed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMinimum Tank Size:\u003c\/strong\u003e\u003cbr\u003eA practical recommendation is at least 500 litres for a single specimen, with a mature, stable system and plenty of swimming space. Larger aquariums are strongly preferred due to its specialist feeding needs and sensitivity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBehaviour \u0026amp; Activity:\u003c\/strong\u003e\u003cbr\u003eThis is an active reef-associated butterflyfish that spends much of the day browsing coral surfaces and moving around reef structure. In nature it is often seen in pairs and can be territorial around feeding areas. In the aquarium it needs open swimming space, mature rockwork, low stress levels and very stable water quality.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReef Safe:\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"text-decoration: underline;\"\u003eNot Reef Safe\u003c\/span\u003e\u003cbr\u003eThis species is not suitable for reef aquariums with corals. It naturally feeds on coral polyps and may also pick at tube worms, clams and other sessile invertebrates. It is best considered a specialist fish-only or expert-only species rather than a normal reef-safe butterflyfish.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecial Requirements or Care Notes:\u003c\/strong\u003e\u003cbr\u003eThis is one of the more difficult butterflyfish to maintain because of its obligate coral-feeding nature. It should only be attempted by experienced marine keepers with a mature aquarium, excellent water quality, peaceful tank mates and a clear plan for frequent specialist feeding. Quarantine and careful acclimation are strongly recommended. Avoid adding to new systems, aggressive fish communities or standard coral reef displays.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSuitable for:\u003c\/strong\u003e\u003cbr\u003eExpert marine fishkeepers only\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAvailability:\u003c\/strong\u003e\u003cbr\u003eRare \/ occasional in trade\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eAll images are a visual representation of the fish you will receive, made to be as accurate as possible.
