If you are obtaining cultured live rock or rubble from this region, there is always a chance to have something extra tagging along. We\u2019ve discovered the occasional odd critter accompanying snails and other cleanup crew ordered from suppliers based in Florida.<\/p>\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"475\" class=\"wp-image-170944\" src=\"https:\/\/reefbuilders.com\/wp-content\/blogs.dir\/1\/files\/2026\/07\/Nudi-Inside-1.png\" alt=\"\" srcset=\"https:\/\/reefbuilders.com\/wp-content\/blogs.dir\/1\/files\/2026\/07\/Nudi-Inside-1.png 640w, https:\/\/reefbuilders.com\/wp-content\/blogs.dir\/1\/files\/2026\/07\/Nudi-Inside-1-20x15.png 20w, https:\/\/reefbuilders.com\/wp-content\/blogs.dir\/1\/files\/2026\/07\/Nudi-Inside-1-385x286.png 385w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\"\/><\/figure>\n<p>While many of these animals are not candidates for a typical reef tank due to dietary needs or predatory behavior, the advent of micro aquariums offers opportunities to maintain and observe some of these critters in isolated settings.
