Its \u003cstrong\u003edeep crimson red body is adorned with clusters of iridescent electric blue spots\u003c\/strong\u003e arranged in radiating bands between its long, dramatic spines — glowing like a constellation of blue eyes staring back at you from across the tank. Under reef lighting, the contrast between the fire-red body and the vivid blue clusters is nothing short of breathtaking.\u003c\/p\u003e\n\u003cp\u003eBeyond its extraordinary appearance, the Blue Eyes Fire Urchin is a tireless and effective member of the cleanup crew. It forages constantly — grazing algae from rockwork, glass, and substrate around the clock as it moves through the tank. As a true omnivore it will also consume detritus, decaying matter, and uneaten food, making it one of the most hardworking and complete natural janitors available in the saltwater hobby.\u003c\/p\u003e\n\u003cp\u003eThis is the rare combination of a functional cleanup animal and a genuine display showpiece — the kind of animal that draws comments from every person who sees your tank for the first time.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3 style=\"color: #1a5a61;\"\u003eAvailable Options\u003c\/h3\u003e\n\u003cdiv style=\"background: linear-gradient(180deg,#f6fbf8 0%, #edf7f2 100%); border: 1px solid #d4e6e3; border-radius: 12px; padding: 13px 15px;\"\u003e\n\u003cp style=\"color: #1a5a61; margin-bottom: 6px;\"\u003e\u003cstrong\u003e1 Blue Eyes Fire Urchin\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOne healthy Blue Eyes Fire Urchin (\u003cem\u003eAstropyga radiata\u003c\/em\u003e)\u003c\/li\u003e\n\u003cli\u003eVibrant red body with electric blue spot clusters — full coloration on display\u003c\/li\u003e\n\u003cli\u003eActive, healthy, and ready to get to work in your system on arrival\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003chr\u003e\n\u003ch3 style=\"color: #184f69;\"\u003eCare Information\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: separate; border-spacing: 10px 10px;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 50%; background: #eceff1; border: 1px solid #cfd6da; border-radius: 10px; padding: 11px 13px; color: #22323a; vertical-align: top;\"\u003e🌡️ \u003cstrong style=\"color: #435760;\"\u003eTemperature\u003c\/strong\u003e\u003cbr\u003e72–78°F\u003c\/td\u003e\n\u003ctd style=\"width: 50%; background: #eceff1; border: 1px solid #cfd6da; border-radius: 10px; padding: 11px 13px; color: #22323a; vertical-align: top;\"\u003e🧂 \u003cstrong style=\"color: #435760;\"\u003eSalinity\u003c\/strong\u003e\u003cbr\u003e1.023–1.026 — drip acclimate carefully on arrival\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background: #eceff1; border: 1px solid #cfd6da; border-radius: 10px; padding: 11px 13px; color: #22323a; vertical-align: top;\"\u003e🐠 \u003cstrong style=\"color: #435760;\"\u003eTemperament\u003c\/strong\u003e\u003cbr\u003ePeaceful — reef safe with caution\u003c\/td\u003e\n\u003ctd style=\"background: #eceff1; border: 1px solid #cfd6da; border-radius: 10px; padding: 11px 13px; color: #22323a; vertical-align: top;\"\u003e⚙️ \u003cstrong style=\"color: #435760;\"\u003eCare Level\u003c\/strong\u003e\u003cbr\u003eEasy to Moderate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background: #eceff1; border: 1px solid #cfd6da; border-radius: 10px; padding: 11px 13px; color: #22323a; vertical-align: top;\"\u003e🍽️ \u003cstrong style=\"color: #435760;\"\u003eDiet\u003c\/strong\u003e\u003cbr\u003eOmnivore — algae, detritus, uneaten food, decaying matter\u003c\/td\u003e\n\u003ctd style=\"background: #eceff1; border: 1px solid #cfd6da; border-radius: 10px; padding: 11px 13px; color: #22323a; vertical-align: top;\"\u003e⚠️ \u003cstrong style=\"color: #435760;\"\u003eVenom\u003c\/strong\u003e\u003cbr\u003eMildly venomous spines — painful but not dangerous\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003ch3 style=\"color: #6a6b58;\"\u003eSpecial Considerations\u003c\/h3\u003e\n\u003cdiv style=\"background: #faf8ee; border: 1px solid #e6e1c9; border-left: 4px solid #b7ad78; border-radius: 10px; padding: 13px 15px; color: #22323a;\"\u003e\n\u003cstrong\u003eHandle with care — the spines of this urchin are mildly venomous and can cause a painful sting if touched directly.\u003c\/strong\u003e Always use gloves or a container when handling.
