Representative Rock flower anemonephoto — a dedicated image of this exact morph isn't available yet.
A dramatic bubble-tip anemone (*Entacmaea quadricolor*) with an inky blue-to-black base/center and contrasting red tentacles. A high-contrast designer look.
📜 Backstory
Aquacultured in-house and sold by Tidal Gardens (which markets it as fully tank-propagated), with similar pieces offered by Corals.com and Top Shelf Aquatics. Treated as a man-made/aquacultured line rather than a wild grade. A bubble-tip, not a rock flower.
Keeper tips for this variant
Keep it under controlled, moderate lighting (too much light can wash out the dark base) on a rocky perch, and feed regularly to maintain the bold contrast.
