{"product_id":"goniastrea-1","title":"Goniastrea","description":"\u003cp\u003eGoniastrea is one of the classic large-polyp stony corals, a familiar sight in reef aquariums for decades. Its encrusting or boulder-like growth forms a solid base covered in a surface of individual corallites, each housing a polyp. These corals are known for their hardiness and steady growth once established in a stable system. Colours can range widely, often in earthy tones like green, brown, and cream, sometimes with contrasting oral discs.\u003c\/p\u003e\n\u003cp\u003eThe surface of a Goniastrea colony has a neat, almost geometric appearance. The corallites are fused together, creating a continuous landscape across the rockwork. At night, its sweeper tentacles can extend, so it's a good neighbour to some but not all corals. During the day, the polyps are generally retracted, showing off the colony's base colouration and structure.\u003c\/p\u003e\n\u003cp\u003eFor care, Goniastrea is quite adaptable. It prefers moderate lighting, somewhere in the 100-200 PAR range is a good target. Too much light can cause it to lose colour. Water flow should be moderate and indirect, enough to keep the surface clean without blasting the tissue. Placement is flexible, from the sandbed to mid-level on the rockwork, as long as its light and flow needs are met. While photosynthetic, it will benefit from occasional target feeding of LPS foods. Like other stony corals, it requires stable alkalinity (8-9 dKH), calcium (420-440 ppm), and magnesium (1300-1400 ppm). Be sure to give it space, as its sweepers can be potent against more peaceful neighbours.\u003c\/p\u003e\n\u003cp\u003eThis coral is a great choice for adding texture and structure to a mixed reef. Its steady, encrusting growth is predictable, and it won.\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":42429159473207,"sku":"EMA-LPS-20260903-PUML","price":70.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1849\/1739\/files\/90dbd438-5bea-4cc7-8d78-8fa0d592836a-_MG_4713.png?v=1788468784","url":"https:\/\/easternmarineaquariums.co.nz\/products\/goniastrea-1","provider":"EasternMarine Aquariums","version":"1.0","type":"link"}
