Sea Fan

About

Found on shallow to mid-depth reef slopes along the Eastern Pacific coast, Pacifigorgia irene is a gorgonian sea fan documented from waters off Costa Rica and the surrounding Central American region. Like other members of its genus, it grows as a flat, branching colony oriented perpendicular to prevailing currents, a form perfectly suited to filter-feeding in high-flow conditions. In the wild it occupies depths of roughly 12 to 33 meters, placing it in moderate to dimmer light zones, which is worth keeping in mind when positioning it in a reef tank. Because source data on this specific species in captivity is limited, husbandry guidance draws largely from what is known about Eastern Pacific gorgonians as a group. These animals are non-photosynthetic or only weakly so, meaning they rely heavily on particulate food and dissolved organics rather than light to sustain themselves. A care requirement that puts them firmly in intermediate territory. Strong, intermittent flow is important to replicate the surge conditions of their native habitat and to prevent detritus settling on the colony. Keepers willing to meet its feeding and flow needs will find it a genuinely interesting and architecturally distinctive addition to a species-appropriate display.
