{"product_id":"open-brain-coral","title":"Open Brain Coral","description":"\u003cp\u003eOpen Brain Corals, often called Trachyphyllia or Wellsophyllia, are a favourite among many reef keepers for their classic LPS appearance and relatively straightforward care. These are classic large polyp stony corals that bring a vibrant, fleshy presence to the aquarium. This piece measures approximately 7cm. Their prominent, wavy folds and rich, sometimes iridescent, colours make them a focal point in any reef. They are typically found in protected, turbid waters on natural reefs. Occasionally, Trachyphyllia will split into two or more heads, increasing their size in the aquarium. This process is fascinating to observe. Open Brain Corals appreciate moderate, indirect flow to keep their tissues clean without causing recession. They thrive under moderate lighting, typically 75-150 PAR, though they can adapt to slightly higher or lower intensities. Placing them directly on the sand bed or a flat, stable rock in the lower to mid-level of the aquarium allows them to fully extend their fleshy polyps. While they host zooxanthellae for their primary nutrition, target feeding with 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. Open Brain Corals are not overly aggressive but do have sweeper tentacles at night, so give them enough room to avoid touching neighbouring corals. When introducing them, a slow drip acclimation over an hour or two is best. Open Brain Corals are a great choice for aquarists looking to add a substantial, colourful, and elegant coral to their display. Their unique shape and often dynamic colouration make them a rewarding addition to a mature reef system.\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":50224957849655,"sku":"EMA-LPS-20260924-RHMO","price":350.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1849\/1739\/files\/b40c467c-802a-45e1-806a-07cbfb1adff9-_MG_5060-2.png?v=1790283280","url":"https:\/\/easternmarineaquariums.co.nz\/products\/open-brain-coral","provider":"EasternMarine Aquariums","version":"1.0","type":"link"}
