📜 Backstory
A named birdsnest sold by World Wide Corals (WWC) as the 'WWC Purple Polyp Birdsnest.' It is a vendor trade-name color form rather than a documented single-collector wild colony, and similar purple-polyp birdsnests are offered by several other shops.
Keeper tips for this variant
Moderate lighting with moderate-to-high flow keeps the colors saturated and the dense branches free of detritus; it is fast growing, so give it room and keep calcium and alkalinity stable.
