{"product_id":"reverse-hammer-coral-4","title":"Reverse Hammer Coral","description":"\u003cp\u003eReverse Hammer Corals, Euphyllia ancora, are a classic and highly sought-after large polyp stony coral in the reef aquarium hobby. Their distinctive hammer-shaped tentacles and flowing movement make them a captivating addition to many reef tanks. This particular piece measures approximately 12cm. They are known for being relatively hardy once settled, making them a good choice for both experienced and newer reef keepers.\u003c\/p\u003e\n\u003cp\u003eEach polyp of the Reverse Hammer Coral has a fleshy, often green or brown stalk that extends into a T-shaped or hammer-like tip, which typically displays a contrasting colour, often a lighter shade of green or cream. These polyps extend significantly during the day, swaying gently in the current and adding dynamic life to the aquarium. At night, they retract somewhat, revealing a calcified skeleton.\u003c\/p\u003e\n\u003cp\u003eFor optimal health, Reverse Hammer Corals appreciate moderate lighting, ideally around 100-200 PAR, though they can adapt to slightly higher or lower intensities with proper acclimation. Moderate, indirect water flow is best, ensuring the polyps gently sway without being blasted. Placement in the mid to lower sections of the rockwork is usually suitable. While they primarily gain nutrients from their zooxanthellae, occasional feeding with small meaty foods like mysis shrimp or brine shrimp can encourage faster growth. Maintain stable water parameters: Calcium 400-440 ppm, Alkalinity 8-10 dKH, Magnesium 1300-1400 ppm, and Salinity 1.025. Like most LPS corals, they can be aggressive; ensure adequate spacing from other corals, as their sweepers can extend several inches at night. Acclimation should be gradual, particularly with light.\u003c\/p\u003e\n\u003cp\u003eReverse Hammer Corals are excellent for adding a focal point with movement and interesting texture. Their robust nature means they often thrive alongside a variety of other reef inhabitants, contributing to a diverse and active display.\u003c\/p\u003e\n\u003cp\u003eThis is a WYSIWYG item, so you'll receive the exact specimen pictured.\u003c\/p\u003e\n\u003cp\u003ePlease note that colours can look slightly different in person than in photos, depending on your lighting and screen, and the size given is an approximate guide measured at the time of listing.\u003c\/p\u003e","brand":"Eastern Marine Aquariums","offers":[{"title":"Default Title","offer_id":50224937140279,"sku":"EMA-LPS-20260924-UICX","price":290.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1849\/1739\/files\/e95468ff-87be-4b5f-8101-4bec9f1d52bf-_MG_5220.png?v=1790280000","url":"https:\/\/easternmarineaquariums.co.nz\/products\/reverse-hammer-coral-4","provider":"EasternMarine Aquariums","version":"1.0","type":"link"}
