{"product_id":"wysiwyg-open-brain","title":"WYSIWYG Open Brain","description":"\u003cp\u003eThis striking Open Brain coral showcases a captivating blend of greens, blues, and purples, creating a vibrant focal point for any reef aquarium. Its fleshy, convoluted polyps create an intricate texture and form, expanding beautifully in the right conditions. This particular specimen is WYSIWYG, meaning you receive the exact coral pictured, ensuring its unique coloration and shape will be a stunning addition to your tank.\u003c\/p\u003e\n\u003cp\u003eOpen Brain corals thrive under moderate to low PAR (Photosynthetically Active Radiation) lighting, typically between 50-150 PAR. Too much light can cause bleaching, while too little can lead to dull coloration and recession. Moderate, indirect water flow is ideal; avoid direct, strong currents that can damage its delicate polyps. Place this coral on a sandy substrate or securely on a rock ledge, ensuring ample space around it as it can extend sweeper tentacles at night. Maintain stable water parameters: temperature 75-79°F, salinity 1.024-1.026, alkalinity 8-12 dKH, calcium 400-450 ppm, and magnesium 1250-1350 ppm.\u003c\/p\u003e\n\u003cp\u003eWhile primarily photosynthetic, benefiting from the symbiotic algae within its tissues, Open Brain corals also appreciate supplemental feeding. Offer finely minced meaty foods such as mysis shrimp, brine shrimp, or specialized coral foods a few times a week, especially in the evening when its feeding tentacles are extended. Target feeding directly to the coral's mouth will encourage faster growth and enhanced coloration. Monitor water quality after feeding to prevent nutrient spikes.\u003c\/p\u003e\n\u003cp\u003eOpen Brain corals are generally peaceful but can extend sweeper tentacles up to several inches at night, capable of stinging neighboring corals. Provide adequate spacing to prevent aggression. Acclimation should be slow and steady, using a drip acclimation method over at least an hour to help the coral adjust to your tank's water parameters. Observe the coral closely for the first few days for signs of stress, such as tissue recession or failure to expand.\u003c\/p\u003e\n\u003cp\u003eAdding this Open Brain coral to your reef tank will provide a stunning display of color and form, offering an engaging visual element. Its relatively easy care requirements make it a rewarding choice for both intermediate and experienced reef keepers.
