{"product_id":"metallic-bronze-hammer-coral","title":"Metallic Bronze Hammer Coral","description":"\u003cp\u003eThe Hammer Coral, Fimbriaphyllia ancora, is one of the most recognisable large polyp stony corals in the reef-keeping hobby. It has been a mainstay in home aquariums for decades for good reason, bringing graceful movement and structure to the reef. This particular branching variety displays a lovely metallic bronze sheen over its base colouration.\u003c\/p\u003e\n\u003cp\u003eIn a home reef, the branching Hammer Coral grows from a calcified base, forming new heads over time. Each polyp is tipped with a distinctive T-shaped or hammer-like vesicle. These polyps gently sway in the current, creating a dynamic display. Under aquarium lighting, the bronze colour develops a subtle metallic finish that can appear to shift as the viewing angle changes. Its tentacles extend during the day and retract slightly at night.\u003c\/p\u003e\n\u003cp\u003eA stable environment is key for any Hammer Coral. They prefer moderate lighting, with PAR levels around 100 to 150 being a safe target. A low to moderate, indirect water flow is ideal to keep the polyps moving without forcing them back against the coral's skeleton. For water parameters, aim for calcium between 420-440 ppm, alkalinity at 8-9 dKH, and magnesium around 1300-1400 ppm. While photosynthetic, they do appreciate occasional target feeding with small meaty foods. Hammer corals are known for their sweeper tentacles, which can extend several centimetres at night, so be sure to give them ample space—at least 10cm—from their neighbours.\u003c\/p\u003e\n\u003cp\u003eThe steady, branching growth of a Hammer Coral makes it a great choice for adding vertical structure to a mixed reef. As it grows, it creates interesting nooks for fish and invertebrates to explore. Its care requirements are straightforward for an LPS coral, making it accessible to anyone who can maintain stable reef parameters.\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":42316445712439,"sku":"EMA-LPS-20260710-04FH","price":295.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1849\/1739\/files\/30c72974-76b9-4e69-987d-1d8e7d3a7322-44-_MG_4342.png?v=1783710948","url":"https:\/\/easternmarineaquariums.co.nz\/products\/metallic-bronze-hammer-coral","provider":"EasternMarine Aquariums","version":"1.0","type":"link"}
