{"product_id":"rastas-zoanthids-zoanthus-sp-b20","title":"Rasta Zoanthids (Zoanthus sp.) (B20)","description":"\u003cp\u003eZoanthids are one of the most beloved and collected corals in the reef hobby, and it is not difficult to understand why. Compact, fast-growing, endlessly variable in colour, and genuinely forgiving of a wide range of water conditions, they offer something for every level of experience and every budget. Whether you are building your first frag rack or hunting down the next piece for a serious zoa garden, these corals deliver immediate visual impact and long-term satisfaction in equal measure. Each polyp is a tiny, disc-shaped flower that opens fully under good conditions to reveal a vivid pattern of rings, halos, and contrasting colours, and no two morphs are exactly alike. Under blue and actinic lighting the effect is spectacular, with colours that fluoresce in ways that photographs rarely do justice.\u003c\/p\u003e\n\u003ch3\u003eWhy we love them\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eExtraordinary colour diversity spanning every part of the spectrum, from electric neons to deep jewel tones to subtle two-tone patterns that reward close observation\u003c\/li\u003e\n\u003cli\u003eFast, reliable growth in stable conditions; established colonies spread steadily and produce frags easily, making them ideal for trading and sharing within the hobby\u003c\/li\u003e\n\u003cli\u003eHardy and adaptable across a broad range of parameters, among the most forgiving corals available for developing reefers\u003c\/li\u003e\n\u003cli\u003eFully compatible with most reef fish and invertebrates and able to coexist in a crowded frag rack or aquascape without specialist care\u003c\/li\u003e\n\u003cli\u003eOne of the most collectible coral groups in the hobby, with an entire community built around hunting, naming, and growing rare and unusual colour morphs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSuggested parameters\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTemperature: 24 to 26°C (75 to 79°F)\u003c\/li\u003e\n\u003cli\u003eSalinity: 1.025 to 1.026 SG\u003c\/li\u003e\n\u003cli\u003epH: 8.1 to 8.4\u003c\/li\u003e\n\u003cli\u003eAlkalinity: 8 to 10 dKH (stability matters most)\u003c\/li\u003e\n\u003cli\u003eCalcium: 400 to 450 ppm\u003c\/li\u003e\n\u003cli\u003eMagnesium: 1250 to 1400 ppm\u003c\/li\u003e\n\u003cli\u003eNitrate: 5 to 20 ppm\u003c\/li\u003e\n\u003cli\u003ePhosphate: 0.03 to 0.12 ppm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCare and placement\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDifficulty: Easy to moderate\u003c\/li\u003e\n\u003cli\u003ePlacement: Lower to mid rockwork, frag racks, sandbed islands, or open rubble zones; avoid placing directly against aggressive sweepers\u003c\/li\u003e\n\u003cli\u003eLighting: Low to moderate; acclimate slowly to higher light to prevent bleaching or browning; most morphs show their best colour under blue-heavy or mixed spectrum lighting\u003c\/li\u003e\n\u003cli\u003eFlow: Low to moderate; enough to keep polyps clean and prevent detritus settling between them, but not so strong that polyps cannot open fully\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeeding\u003c\/h3\u003e\n\u003cp\u003eNot required, but optional feeding supports faster growth and enhanced colour.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFine coral foods, reef roids style powders, or phytoplankton broadcast once or twice per week\u003c\/li\u003e\n\u003cli\u003eTurn pumps down before feeding and resume flow after 10 to 15 minutes to allow polyps to feed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility and spacing\u003c\/h3\u003e\n\u003cp\u003eZoanthids are generally peaceful but will compete for space over time.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLeave room between morphs if you want to maintain clean borders between colonies; zoas will grow into and over neighbouring frags if left unchecked\u003c\/li\u003e\n\u003cli\u003eKeep away from aggressive sweeper corals including torches, hammers, favias, and other large LPS that will sting and kill zoa polyps at the colony's edge\u003c\/li\u003e\n\u003cli\u003eMost reef safe fish and invertebrates are compatible, though some fish, including certain butterflyfish and wrasses, may nip at polyps\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eImportant handling note\u003c\/h3\u003e\n\u003cp\u003eZoanthids and palythoas can contain palytoxin, one of the most potent naturally occurring toxins known. Always wear gloves and eye protection when fragging, handling, or working near colonies, and wash hands and all tools thoroughly after contact. Avoid any situation where the coral tissue could be aerosolized, such as cutting under running water or near a fan. If you have open cuts on your hands, double-glove. Take this seriously every time, no exceptions.\u003c\/p\u003e\n\u003ch3\u003eWhat you are buying\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eYou will receive a zoanthid frags with 3-6 polyps\u003c\/li\u003e\n\u003cli\u003eColour and polyp size can vary between systems and may shift during acclimation as the coral adjusts to new lighting, flow, and nutrient levels; this is normal and colours typically stabilize and intensify once the colony is fully settled\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Little Shop of Coral","offers":[{"title":"Default Title","offer_id":53575537787153,"sku":null,"price":50.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/5196\/6737\/files\/RastaZoa.png?v=1779802596","url":"https:\/\/littleshopofcoral.ca\/products\/rastas-zoanthids-zoanthus-sp-b20","provider":"Little Shop of Coral","version":"1.0","type":"link"}
