About

Found along the tropical coastlines of the Eastern Pacific, including the waters off Costa Rica and Central America, Leptogorgia exigua is a sessile octocoral that anchors itself to hard substrate and filters food from the passing current. Like most gorgonians, it forms branching, tree-like colonies that can become a genuine focal point in a mature reef display, though it requires a keeper who understands its needs rather than someone just getting started with coral care. High, consistent water movement is probably the single most important factor for keeping this coral healthy. It depends on strong flow both to deliver food particles and to prevent sediment from smothering its delicate polyps. Feeding small-particle foods like phytoplankton and zooplankton regularly will go a long way toward keeping colonies thriving, since non-photosynthetic or low-light gorgonians lean heavily on what they can capture rather than what they can photosynthesize. Placement matters too: position it where flow is vigorous but not so turbulent that the branches are constantly whipping around. This is not the most demanding coral in the sea, but it rewards attentive husbandry and punishes neglect fairly quickly, making it a solid intermediate-level project for a reefer ready to move beyond the basics.
