Common name: Manjano Anemone

General information

The Manjano Anemone, Anemonia manjano, is a small and brightly colored anemone species that is often found in the aquarium trade. Despite its attractive appearance, it is considered a pest anemone by many reefkeepers due to its rapid reproduction rate and tendency to overtake other sessile invertebrates in the aquarium.

Care

Manjano Anemones require moderate to high lighting and water flow to thrive. They can be difficult to remove once established, as they can reproduce asexually through pedal laceration, where small pieces of the foot break off and develop into new individuals. Chemical treatments or manual removal are often necessary to control their population in the aquarium.

Reproduction

Anemonia manjano reproduces both sexually and asexually. Sexual reproduction occurs through the release of gametes into the water column, while asexual reproduction is more common in the aquarium setting. Asexual reproduction can lead to rapid population growth, making them a nuisance if not managed properly.

Symbiosis

While not hosting clownfish like their larger cousins, Manjano Anemones may engage in symbiotic relationships with certain types of zooxanthellae, which are photosynthetic algae that live within their tissues. This symbiosis allows the anemone to receive nutrients from the algae's photosynthesis, contributing to their growth and coloration.

Habitat

In the wild, Anemonia manjano is typically found in shallow, warm waters where it attaches to hard substrates. They are often seen in areas with strong lighting, which is essential for the zooxanthellae living within their tissues.
