{"product_id":"a-grade-orange-hammer-coral","title":"A Grade Orange Hammer Coral","description":"\u003cp\u003eHammer corals, or Euphyllia ancora, are a cornerstone species in the LPS coral hobby. Their distinctive, hammer-shaped tentacles make them easily recognisable and a favourite for many aquarists. This orange variety brings a vibrant pop of colour to a reef tank. They are generally considered moderately challenging to care for, rewarding consistent water parameters with excellent growth and polyp extension.\u003c\/p\u003e\n\u003cp\u003eThis coral exhibits a classic branching growth form, with its polyps extending fully to reveal their signature hammer-like tips. The polyps are a rich, striking orange, often with lighter tips that shimmer under appropriate lighting. When happy, their polyps will inflate significantly, swaying gently in the current. This piece measures approximately 10cm, making it a substantial addition to a mature display.\u003c\/p\u003e\n\u003cp\u003eFor optimal health, Hammer corals thrive under moderate lighting, typically 75-150 PAR. Flow should be moderate and indirect, ensuring the polyps sway without being battered against the skeleton. Placement can be on the sand bed or securely attached to rockwork in the lower to mid sections of the tank, where they can extend fully without touching other corals. They are photosynthetic but benefit from supplemental feeding of small meaty foods like mysis shrimp or copepods a few times a week. Maintain stable water parameters: Calcium 400-440 ppm, Alkalinity 8-10 dKH, and Magnesium 1300-1400 ppm. Hammer corals can be aggressive due to their long sweeping tentacles, so ensure ample spacing from neighbouring corals. Acclimation should be gradual, particularly to new lighting conditions.\u003c\/p\u003e\n\u003cp\u003eHammer corals provide excellent movement and an anchor point for tank aesthetics. Their large, flowing polyps add a dynamic element to any reef.\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":50224976658487,"sku":"EMA-LPS-20260924-OH5A","price":700.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1849\/1739\/files\/579e6640-a0ab-4398-81e5-ac4c08ea1eb8-_MG_4985.png?v=1790284258","url":"https:\/\/easternmarineaquariums.co.nz\/products\/a-grade-orange-hammer-coral","provider":"EasternMarine Aquariums","version":"1.0","type":"link"}
