{"product_id":"pencil-urchin-large","title":"Pencil Urchin (Eucidaris tribuloides)","description":"\u003cp\u003eEucidaris tribuloides belongs to a lineage of urchins that's barely changed since the Triassic, and the thick, blunt spines behind its common name are essentially the same design that's been grazing reefs for a couple hundred million years — a stark contrast to the thin, needle-sharp spines on most other urchins in the trade. That blunt profile makes it a much safer urchin to handle, though it'll still graze coralline algae and the occasional coral polyp if algae runs short, so it's not entirely hands-off in a reef. Slow-moving and mostly nocturnal, spending daylight tucked into crevices with just the spine tips showing.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eCare level: Easy · Temperament: Peaceful · Max size: ~3\" body (spines add reach) · Min tank: 30 gal · Reef safe: With caution (may graze coral\/coralline) · Diet: Omnivore, algae + detritus\u003c\/em\u003e\u003c\/p\u003e","brand":"YoCamron's Exotics","offers":[{"title":"Large \/ Quarantined","offer_id":50311981564141,"sku":"TURCH5506","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Large \/ Non-Quarantined","offer_id":50337339605229,"sku":"TURCH5506","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0806\/1032\/8813\/files\/lg-79388-urchin.jpg?v=1786966655","url":"https:\/\/yocamronsaquatics.com\/products\/pencil-urchin-large","provider":"YoCamron's Exotics","version":"1.0","type":"link"}
