Representative Bubble tip anemonephoto — a dedicated image of this exact morph isn't available yet.
A dramatic morph with an inky blue-to-black base and oral disc set against bright red (and sometimes pink) bubble tentacles, with a starry speckled center. A standout 'designer' BTA.
📜 Backstory
Aquacultured and sold by Tidal Gardens (grown in-house), and also offered by Corals.com, Top Shelf Aquatics, Vivid Aquariums and Aquarium Reefers; an 'ECC Black Widow' line is offered through Eye Catching Coral / Oceans Garden. It is one of the more sought-after BTA color morphs, propagated as captive splits rather than tied to a single named collector, so origin is best described as an aquacultured designer line (lineage debated).
Keeper tips for this variant
Moderate-to-high light (PAR ~220-350) deepens the blue/black base and red contrast; pair with moderate flow on a secure rock perch. Never run an anemone through coral dip, which can kill it.
