Representative Pulsing xeniaphoto — a dedicated image of this exact morph isn't available yet.
A Cespitularia-genus 'blue xenia' (a close xenia relative, not a true Xenia) with shimmering powder-blue to violet stalks and contrasting pale polyps, far more colorful than ordinary tan xenia.
📜 Backstory
Sold as 'Blue Cespitularia / Blue Xenia' by ORA, LiveAquaria (CCGC aquacultured), Cornbred Corals ('Cornbred's Blue Cespitularia Xenia') and SaltCritters, who flag it as a 'rare blue xenia.' It is collected from Indo-Pacific reefs; lineage of individual vendor pieces is largely undocumented, so specific naming origins are debated.
Keeper tips for this variant
Less forgiving than true Xenia: keep very stable nutrients, strong-ish flow and brighter light to hold the blue, and avoid sudden parameter swings that cause it to melt.
