🐠 Blotched Anthias (Odontanthias borbonius)
A Soft Pink-Lavender Body With Golden Blotches • Tall, Elegant Violet-Blue-Green Fins • A Rare, Cool-Water Centrepiece
📋 The Blotched Anthias, also known as the Borbonius Anthias, is a spectacular deep-water fish with a soft pink-to-lavender body scattered with irregular golden-yellow blotches, accented by violet, blue, and green highlights along tall, elegant fins.
It ranges across a wide stretch of the Indo-Pacific, from South Africa to Palau, north to Japan and south to Indonesia, on mesophotic and deep rocky reefs at roughly 70-300 metres, considerably deeper than most reef fish in the trade, staying close to caves and protected ledges where light is naturally dim and water stays cool. Every Blotched Anthias we ship is feeding well.
It's a true centrepiece for an advanced, chiller-equipped system: it needs meaningfully cooler water than a typical reef tank, dim or shaded lighting, especially during the first weeks, and a large, mature setup with extensive caves and ledges. It's fully reef safe, and captive-bred stock from specialist facilities such as Biota Palau occasionally becomes available as a lower-impact alternative to wild collection. It reaches up to 15cm, so plan on at least 380L.
