{"product_id":"red-trachyphyllia-7","title":"Red Trachyphyllia","description":"\u003cp\u003eThe Open Brain Coral, Trachyphyllia geoffroyi, is a classic large-polyp stony coral that has been a favourite in the hobby for decades. It is a free-living coral, meaning it doesn't encrust on rockwork, making it a unique feature for the sandbed of a home reef. This particular specimen displays the solid red colouration that makes these corals so popular.\u003c\/p\u003e\n\u003cp\u003eA healthy Trachyphyllia can inflate its tissue to a surprising size, often hiding its conical skeleton completely. The surface of this specimen is a rich, uniform red, with convoluted folds that catch the light in different ways as the coral expands and contracts. At night, it may extend its feeder tentacles, revealing a different side of its behaviour. Its ability to change shape throughout the day is one of its most interesting qualities.\u003c\/p\u003e\n\u003cp\u003eCare for the Red Trachyphyllia is straightforward in a stable reef environment. It requires low to moderate lighting, ideally in the 75-150 PAR range, as too much light can cause it to retract. Place it on a soft sandy bottom, well away from sharp rocks that could puncture its soft tissue. Flow should be low and indirect, just enough to keep it clean without battering the polyp. It benefits greatly from weekly target feeding with meaty foods like mysis or brine shrimp. Maintain stable alkalinity (8-9 dKH), calcium (420-440 ppm), and magnesium (1300-1400 ppm). While not overly aggressive, it should be given several inches of space to avoid any potential contact with neighbouring corals.\u003c\/p\u003e\n\u003cp\u003eAs a solitary sand-dweller, the Open Brain coral is an excellent choice for adding life to the bottom of a tank. It doesn’t spread or grow invasively, making it a predictable and manageable centerpiece for that area. It coexists peacefully with most reef inhabitants, though care should be taken with any fish known to nip at fleshy corals.\u003c\/p\u003e\n\u003cp\u003eThis is a WYSIWYG item, so you'll receive the exact specimen pictured.\u003c\/p\u003e","brand":"Eastern Marine Aquariums","offers":[{"title":"Default Title","offer_id":42359272439863,"sku":"EMA-LPS-20260807-HUKJ","price":145.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1849\/1739\/files\/ea4ab331-a509-47db-bd02-d472c1ef5a53-_MG_4541.png?v=1786132072","url":"https:\/\/easternmarineaquariums.co.nz\/products\/red-trachyphyllia-7","provider":"EasternMarine Aquariums","version":"1.0","type":"link"}
