A birdsnest carrying a light green-to-blue color gradient across its polyps and thin tangled branches, standing apart from the more common solid pink and green forms.
📜 Backstory
A captive-created hybrid Seriatopora documented by Reef Builders and reef2reef: it resulted from an accidental aquarium spawning at Lazy's Coral House between a green-polyp birdsnest and the ORA Bird of Paradise, and is cited as one of the first confirmed crosses between two aquarium SPS strains. It is propagated and sold by Tidal Gardens as 'Blue Zing Bird's Nest Seriatopora' and circulates through other shops such as Queen City Corals.
Keeper tips for this variant
Run it under blue-heavy lighting to bring out the blue tone and provide moderate flow through the dense branch cluster to prevent dead spots; keep alkalinity stable for steady tip growth.
