Bubble Tip Anemone: Small Black Widow Live Reef Invertebrate for Stable, Well-Lit Saltwater Aquariums

Bring vivid, flowing movement to an established reef aquarium with this small Black Widow Bubble Tip Anemone. Its tentacles create an engaging display, while its ability to host clownfish can add a fascinating natural interaction to a compatible reef community.

This living invertebrate anchors with a muscular foot but may reposition when lighting, flow, or water conditions are unsuitable. Careful placement and guarded powerheads make its movement easier to manage.

Stable water chemistry, moderate-to-high lighting, and moderate indirect flow are central to its routine care. Gradual light acclimation and small supplemental meals support healthy expansion and coloration.

Key Features

• Flowing tentacles add natural motion to the aquarium, creating an eye-catching focal point in a thoughtfully arranged reef display.
• Its muscular foot attaches to reef surfaces and allows repositioning, giving the anemone a way to seek more suitable conditions within the tank.
• The species can host clownfish, bringing a recognizable symbiotic interaction to compatible marine aquarium communities.
• Moderate-to-high lighting supports its symbiotic zooxanthellae, which supply essential nutrients through photosynthesis.
• Moderate indirect flow lets the tentacles sway without being blasted, while carrying nutrients and waste through the surrounding water.
• Small meaty foods offered once or twice weekly supplement its photosynthetic energy and support growth, health, and coloration.
• Gradual acclimation to new lighting reduces stress when the anemone is introduced to a different aquarium setup.
• Powerhead guards protect this mobile invertebrate from pump intakes if it begins moving around the aquarium.
