Scientific name: Boloceroides mcmurrichi (Kwietniewski, 1898)
Swimming sea anemone in blue water, Boloceroides mcmurrichi

General information

The Bulb Anemone, Boloceroides mcmurrichi, is a distinctive species of sea anemone known for its large, bulbous tentacles and vibrant coloration, which can range from deep purples to bright greens. Unlike many other anemones, this species does not typically host clownfish or other symbiotic fish. It is a solitary creature that can be quite mobile, often moving around the aquarium to find an ideal spot with suitable lighting and flow.

Care

Bulb Anemones require a well-established aquarium with stable water parameters. They prefer moderate to high lighting and moderate water flow. It's important to provide a sandy substrate or rock crevices where they can anchor their base. Feeding should consist of meaty foods like shrimp, fish, and other suitable marine-based foods. Care should be taken to ensure that the anemone does not come into contact with powerheads or heaters, as this can cause injury.

Reproduction

In the aquarium, Boloceroides mcmurrichi can reproduce asexually through a process called pedal laceration, where pieces of the base detach and develop into new anemones. Sexual reproduction is less common in captivity but involves the release of gametes into the water column.

Habitat

Bulb Anemones are found in the Indo-Pacific region, typically in shallow waters on reef slopes or within lagoons. They attach to both hard and soft substrates, adjusting their location as needed to optimize their exposure to light and prey availability.
