Description
Black Widow Bubble Tip Anemone (Entacmaea quadricolor)
The Black Widow Bubble Tip Anemone (BTA) is one of the most prized designer Bubble Tip Anemones. It features deep blackish-red to burgundy tentacles, an intense crimson to red oral disc, and brilliant fluorescent highlights under blue reef lighting. Healthy specimens often develop bubble-shaped tentacle tips, although tentacle shape can vary depending on flow, lighting, and feeding. It is an excellent natural host for many clownfish species and makes a stunning centerpiece in reef aquariums.
