Representative Sun coralphoto — a dedicated image of this exact morph isn't available yet.
A dramatic tree-like coral with a near-black, dark-brown or greenish-black branching skeleton and large polyps that often glow fluorescent green when open — the only branching (dendroid) species in *Tubastraea* (*T. micrantha*).
📜 Backstory
*Tubastraea micrantha*, the 'Black Sun,' was profiled by Reef Builders as 'the most majestic azoox coral' and is famously found blanketing structures and oil platforms in the wild. Wild-collected and sold as branched black sun/tube coral by LiveAquaria, FreshMarine, SaltwaterFish and others. Notoriously demanding; its dendroid (branching) growth distinguishes it from all other massive, dome-shaped *Tubastraea*.
Keeper tips for this variant
Mount upright in a shaded cave with moderate-to-strong current; it is the touchiest sun coral, so feed heavily and consistently — survival is poor for under-fed colonies, which makes it the hardest of the group to keep long-term.
