Sea hares can be quite voracious, removing large swaths of nuisance algae from rock and glasswork in a matter of days, depending on tank size. Unfortunately, sea hares can sometimes be TOO efficient at clearing the algae out of an aquarium and starve themselves unless supplemented with offerings of various dried seaweed species anchored to a surface for easy access. In extremely rare instances of stress, sea hares can produce an ink-like substance as a defense mechanism; This ink is toxic to many other reef inhabitants and if observed, should be removed immediately via a large water change.\u003c\/span\u003e\u003c\/p\u003e","brand":"TSA Inverts","offers":[{"title":"Default Title","offer_id":49117732765994,"sku":"SLUGxSeaHare","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/0873\/7322\/files\/tsa-inverts-dolabella-sea-hare-1251624973.png?v=1785446679"},{"product_id":"tuxedo-urchin","title":"Tuxedo Urchin","description":"\u003cp\u003e\u003cspan style=\"font-weight: 400;\" data-mce-fragment=\"1\" data-mce-style=\"font-weight: 400;\"\u003eSea Urchins are incredible powerhouses when it comes to clearing algae out of a reef.

When disturbed, they quickly retract into their protective tube, making them fascinating to observe without adding aggression or bioload concerns.
