That soft, folded dome carries a mix of neon reds, greens and rainbow tones that make it one of the more eye-catching pieces on the sandbed.\u003c\/p\u003e\u003ch2\u003eSpecies\u003c\/h2\u003e\u003cp\u003eAA019 is a Trachyphyllia geoffroyi, commonly sold as the Open Brain coral. It has a reputation as a hardy and forgiving choice, tolerant of a range of aquarium conditions while still delivering strong, saturated colour.\u003c\/p\u003e\u003ch2\u003eWhere It Comes From\u003c\/h2\u003e\u003cp\u003eIn the wild this species does not attach to rock at all - it lies free on soft sediment in sheltered lagoons and inter-reef zones throughout the Indo-Pacific, including reefs in northern Australia. These are lower-light, gently-flowing, slightly nutrient-enriched habitats, so AA019 should be rested directly on the sandbed in a calm, low-flow spot in the tank rather than propped up among rocks, where its delicate underside could be damaged.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Default Title","offer_id":55611893055779,"sku":"AA5571","price":65.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/AA043-open-brain-20K_2cb7c5f7-6ad1-4e5e-be20-54b2cb0f19c9.jpg?v=1789706279"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/collections\/TR9030001_ab4eab73-472b-4532-b08f-7a2cfaf28cc7.jpg?v=1788485884","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/collections\/trachyphyllia-geoffroyi.oembed","provider":"Nicks AOT","version":"1.0","type":"link"}
