Common name: Strawberry Anemone

Scientific name: Actinia fragacea Tugwell, 1856

General Information

The Strawberry Anemone, scientifically known as Actinia fragacea, is a striking and colorful sea anemone species that is sure to catch the eye of any marine enthusiast. Its vibrant red body, often adorned with green or white spots resembling strawberry seeds, makes it a visually stunning addition to coldwater marine aquariums. Native to the northeastern Atlantic Ocean, this species is commonly found along rocky shorelines and intertidal zones, where it thrives in cooler waters.

While not as commonly kept as tropical anemones, the Strawberry Anemone is a fascinating choice for coldwater marine setups. Its unique appearance and relatively hardy nature make it an appealing option for aquarists looking to diversify their collections. However, its care requirements differ significantly from those of tropical anemones, so it is best suited for experienced hobbyists.

Care

The Strawberry Anemone requires a coldwater marine aquarium with stable water parameters. A chiller is often necessary to maintain the cooler temperatures this species prefers. It thrives in tanks with rocky substrates and plenty of crevices, mimicking its natural habitat. Strong water flow is also essential, as it helps to deliver nutrients and oxygen to the anemone.

This species is relatively hardy but requires careful acclimation to its new environment. It is sensitive to sudden changes in water parameters, so maintaining consistency is key. Regular monitoring of water quality, including nitrate and phosphate levels, is crucial to its health.

Diet and Feeding

In the wild, the Strawberry Anemone is a carnivore, feeding on small fish, plankton, and other tiny marine organisms. In captivity, it can be fed a diet of finely chopped seafood, such as shrimp, fish, and squid, as well as frozen or live plankton. Target feeding using a turkey baster or similar tool ensures that the anemone receives adequate nutrition.

Feed the anemone once or twice a week, offering small portions that it can consume within a few minutes. Overfeeding can lead to water quality issues, so it is important to monitor its intake and adjust feeding schedules as needed.

Behavior and Compatibility

The Strawberry Anemone is generally peaceful but can exhibit aggressive behavior towards other anemones or corals if they encroach on its territory. It uses its stinging tentacles to defend itself and capture prey, so care should be taken when placing it in a tank with other sessile invertebrates.

This species is best kept in a species-specific tank or with other coldwater marine organisms that share similar environmental requirements. Avoid housing it with tropical species, as the temperature differences can be detrimental to both the anemone and its tank mates.

Symbiosis

Unlike tropical anemones, the Strawberry Anemone does not form symbiotic relationships with clownfish. However, it plays an important role in its natural ecosystem by providing shelter for small marine organisms and contributing to the biodiversity of rocky shorelines.

Health and Common Issues

With proper care, the Strawberry Anemone can live for several years in captivity. Maintaining stable water parameters and a consistent feeding schedule are key to its longevity. Common health issues include tissue recession and bleaching, often caused by poor water quality or inadequate nutrition. Regular water changes and careful monitoring can help prevent these problems.

When selecting a Strawberry Anemone, look for specimens with vibrant coloration and fully extended tentacles. Avoid individuals with signs of damage or discoloration, as these may indicate underlying health issues.

Habitat

The Strawberry Anemone is native to the northeastern Atlantic Ocean, including the coasts of the United Kingdom, Ireland, and parts of northern Europe. It inhabits rocky shorelines, intertidal zones, and shallow subtidal areas, where it attaches to rocks and other hard surfaces. This species prefers cooler water temperatures and thrives in areas with strong water flow and abundant plankton.

In captivity, replicating these conditions is essential for its health and well-being. A coldwater marine aquarium with plenty of live rock and strong water movement provides an ideal environment for this stunning anemone.
