Snake Polyp

About

Snake polyps (Isaurus tuberculatus) are an unusual zoanthid that stand apart from the typical flat, disc-shaped polyps most reef keepers are familiar with. Each individual polyp extends into a noticeably elongated, tube-like column covered in small bumps or tubercles, giving the colony a texture and silhouette unlike most of its zoanthid relatives. Hence the common name. Found across both the Western Pacific and Atlantic, including reef systems in the Caribbean such as the barrier reef off Belize, this species occupies shallow coastal and reef habitats from the surface down to around 20 meters. In the wild it grows as a sessile colonial organism, anchoring itself to hard substrate and forming spreading clusters over time. In the aquarium, snake polyps are considered a reasonable choice for those newer to keeping soft corals. They appreciate moderate water movement and moderate lighting, which makes them fairly flexible when it comes to placement within a mixed reef tank. They are considered reef safe and generally mind their own business around other corals and invertebrates. Source data on this species is relatively limited in the hobby, but their straightforward requirements and distinctive appearance make them a genuinely interesting addition for a keeper looking for something a little different from the usual zoanthid fare.
