{"product_id":"zoanthid-fragment-41","title":"Zoanthid Fragment","description":"\u003cp\u003eZoanthids are a reef aquarium classic, found in almost every kind of system from nano tanks to large-scale displays. These colonial polyps are known for their bright colours and relative hardiness, making them a common entry point into the coral-keeping hobby. They belong to a wide-ranging group, with countless colour variations found in the wild.\u003c\/p\u003e\n\u003cp\u003eEach zoanthid polyp consists of a central oral disc surrounded by a skirt of tentacles. They grow attached to a common fleshy mat, encrusting over rockwork and forming dense colonies over time. Under actinic lighting, many varieties will fluoresce, with colour combinations ranging from greens and browns to oranges, pinks, and yellows. The polyps will close up at night or when disturbed, but typically remain open during the daytime.\u003c\/p\u003e\n\u003cp\u003eFor care, zoanthids are quite adaptable. They do well under a wide range of lighting, from lower intensity PAR around 50-75 up to moderate levels of 150-200. Flow should be moderate and indirect to keep the polyps clear of detritus without blasting them shut. While largely photosynthetic, they can benefit from occasional small particle foods. Maintain stable water parameters with calcium around 420-440 ppm, alkalinity at 8-9 dKH, and magnesium at 1300-1400. Be mindful that some zoanthids can contain palytoxin, so it's wise to wear gloves and eye protection when handling them out of water.\u003c\/p\u003e\n\u003cp\u003eDue to their encrusting nature, it's best to place them on an isolated rock or on lower rockwork where their growth can be managed. They aren't aggressive in the typical sense of sweeper tentacles, but they will grow over and smother neighbouring corals that can't defend themselves. Given some space, they create a living carpet of colour that adds mature, established texture to the reef.\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":42403875323959,"sku":"EMA-SOF-20260821-UQOR","price":55.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1849\/1739\/files\/dd7166f0-a31d-40e7-9e33-6d7d5fce462f-_MG_4648.png?v=1787345903","url":"https:\/\/easternmarineaquariums.co.nz\/products\/zoanthid-fragment-41","provider":"EasternMarine Aquariums","version":"1.0","type":"link"}
