📜 Backstory

Black Widow BTAs are an established, sought-after strain of Entacmaea quadricolor known for a dark body and contrasting bright tips, propagated in the hobby by splitting. The exact origin is debated and no single founder is documented, but the name is well recognized across major vendors. They fetch premium prices because the dark pigment paired with bright tips is uncommon and slow to multiply.

Keeper tips for this variant

Strong blue-heavy light brings out the neon tips against the dark body; anchor it on rock with moderate flow and feed regularly to keep the dark pigment intense.
