{"product_id":"toxic-green-hammer-coral","title":"Toxic Green Hammer Coral","description":"\u003cp\u003eHammer corals, Euphyllia ancora, are a classic choice for reef keepers, prized for their flowing polyps and vibrant colours. This particular specimen presents a stunning toxic green hue, making it a focal point in any reef aquarium. Its distinctive tentacles move gracefully with tank currents, adding dynamic visual interest. This piece measures approximately 14cm. Some aquarists find them a good \"starter\" LPS, though they still require stable conditions to truly thrive. This green Hammer coral is a good representation of why these corals remain popular in the hobby. Its vibrant toxic green colouring is consistent across its polyps. Individual polyps extend from a central skeletal structure, swaying gently as they capture food. Hammer corals can be found in a branching or wall formation; this specimen exhibits a branching growth pattern, with multiple heads emerging from a solid base. Keep lighting in the moderate range, around 75-150 PAR, to maintain its health and colouration. A lower to mid-tank placement is generally ideal, ensuring it receives appropriate light without being overwhelmed. Flow should be moderate and indirect, enough to keep detritus from settling but not so strong as to cause the polyps to retract or be damaged. While they host zooxanthellae for most of their nutritional needs, target feeding with small meaty foods like mysis shrimp or copepods a few times a week will promote faster growth and better health. Maintain stable water parameters: Calcium 400-440 ppm, Alkalinity 8-10 dKH, and Magnesium 1300-1400 ppm. Hammer corals can be aggressive, with sweeper tentacles that extend at night, so give this green specimen ample space from other corals to prevent stinging. Proper acclimation is crucial; use a slow drip acclimation method over several hours to minimise stress from changes in water chemistry.\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":50224942022711,"sku":"EMA-LPS-20260924-X3BB","price":380.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1849\/1739\/files\/f3ee670e-ab3b-48e9-87f5-2f4234e92ad9-_MG_5204.png?v=1790280669","url":"https:\/\/easternmarineaquariums.co.nz\/products\/toxic-green-hammer-coral","provider":"EasternMarine Aquariums","version":"1.0","type":"link"}
