Common name: Beadlet Anemone

General Information

The Beadlet Anemone, scientifically known as Actinia equina, is a fascinating and hardy species of sea anemone commonly found along the rocky shores of the Atlantic Ocean, Mediterranean Sea, and parts of the North Sea. Its striking appearance, characterized by its bright red, green, or brown coloration, makes it a popular choice for marine enthusiasts looking to add a splash of color to their aquariums. This species is relatively small and compact, with a smooth, columnar body and tentacles that retract when disturbed, giving it a bead-like appearance—hence the name.

Actinia equina is an excellent choice for aquarists who want a low-maintenance anemone. Its ability to tolerate a range of environmental conditions, including varying salinity and temperature levels, further contributes to its popularity among hobbyists.

Care

The Beadlet Anemone is a hardy species that adapts well to life in captivity, provided its basic needs are met. It thrives in aquariums with stable water parameters and moderate lighting. It appreciates a tank setup that mimics its natural rocky habitat. Providing crevices and overhangs will allow the anemone to anchor itself securely and feel protected.

This species is relatively low-maintenance and does not demand specialized care, making it suitable for beginners. However, it is essential to monitor water quality and maintain stable salinity and temperature levels to ensure its long-term health.

Diet and Feeding

In the wild, Actinia equina is a carnivorous species that feeds on small fish, plankton, and other organic matter carried by the currents. In captivity, it can be fed a diet of finely chopped seafood, frozen mysis shrimp, or other meaty marine foods. Feeding should be done sparingly, as overfeeding can lead to water quality issues.

Offer food directly to the anemone using feeding tongs or a pipette, ensuring that the food is small enough for it to consume. Feeding once or twice a week is sufficient to meet its nutritional needs.

Behavior and Compatibility

The Beadlet Anemone is generally peaceful but can exhibit territorial behavior if placed too close to other anemones or corals. It uses its stinging tentacles to defend its space, so care should be taken when positioning it in a reef tank. It is best kept as a solitary specimen or with other species that are not prone to being stung.

This anemone is not toxic to humans but should still be handled with care to avoid irritation from its nematocysts. It is compatible with a variety of reef-safe fish and invertebrates, provided they do not attempt to prey on it.

Reproduction

Actinia equina reproduces both sexually and asexually. In sexual reproduction, it releases gametes into the water column, where fertilization occurs. Asexually, it can reproduce through fission, where the anemone splits into two genetically identical individuals. This ability to propagate easily makes it a resilient species in both the wild and captivity.

Habitat

The natural habitat of the Beadlet Anemone includes rocky intertidal zones, where it attaches itself to rocks, crevices, and other hard substrates. It is well-adapted to withstand exposure during low tide, retracting its tentacles and forming a protective mucus layer to retain moisture. This adaptability makes it a robust species capable of thriving in various environmental conditions.

In the aquarium, replicating its natural habitat with rocky structures and moderate water flow will help it feel at home. While it can tolerate a range of salinity levels, maintaining a stable environment is crucial for its health.
