The Red Bubble Anemone (Entacmaea quadricolor) is a stunning addition to any saltwater reef aquarium. With its vibrant red coloration and unique bulb tip, this anemone is sure to capture attention.

This member of the Actinide family is known for its impressive feeding behavior. When hungry, it extends its sweeper tentacles to snatch food from the water column. After a satisfying meal, the tentacles retract and take on their bulbous appearance.

Coloration can vary greatly among individuals. Red variations, also known as Rose Anemones, are particularly eye-catching. Anemones from Fiji and Tonga display shades of soft browns, tans, or maroon, while those from Singapore are typically green with a deep maroon base.

Found in oceans worldwide, the Bulb Anemone attaches itself deep within dead coral or on solid, living reefs. In the home aquarium, it thrives amongst deeply creviced live rock or branchy corals placed in sandy substrate.

While the Bulb Anemone may explore your aquarium before settling on a preferred location, it should be positioned under strong lighting in tanks of at least 30 gallons. Under ideal conditions, it can grow up to 1-ft in diameter, but it usually remains compact under bright lighting.

For optimal care, keep a clownfish as a tank mate. If the lighting is insufficient, the Bulb Anemone will expand its body to maximize available light. Feeding it a diet of chopped fish, shrimp, or worms is necessary when not hosting a clownfish.

Handle this magnificent invertebrate, and any anemone, with care. With its breathtaking appearance and captivating behavior, the Red Bubble Anemone is sure to be the highlight of your saltwater aquarium.
