Common name: Marine Blue Flatworm

General Information

The Marine Blue Flatworm, scientifically known as Cycloporus venetus, is a captivating species often admired for its striking appearance. With its vivid blue coloration and flat, ribbon-like body, it stands out in any marine setting. Although not commonly kept in home aquariums, this flatworm is occasionally sought after by hobbyists intrigued by its unique form and movement.

While not a major player in the aquarium trade, the Marine Blue Flatworm is of interest to those who appreciate the diversity of marine life. Its presence in an aquarium can serve as an educational tool, providing insights into the complexity and beauty of marine ecosystems. However, it is essential to note that this species can be challenging to care for, requiring specific conditions to thrive.

Care

Marine Blue Flatworms demand specific care to maintain their health in captivity. They thrive in tanks that closely mimic their natural reef environments, with stable water conditions and plenty of live rock for grazing. These flatworms are sensitive to changes in water quality, so maintaining pristine conditions is crucial.

Creating an environment rich in microfauna is beneficial, as this forms the basis of their diet. Additionally, providing ample hiding spots and a calm environment helps reduce stress, which can be detrimental to their health.

Diet and Feeding

In the wild, Marine Blue Flatworms are primarily detritivores, feeding on detritus and microfauna found on live rock and substrate. In captivity, they require a diet that replicates these natural conditions. Offering a variety of microfauna and detritus can help meet their nutritional needs.

Feeding should be consistent, ensuring they have access to sufficient food sources to prevent starvation. It is important to monitor their feeding habits and adjust the environment to promote the growth of natural food sources.

Behavior and Compatibility

Marine Blue Flatworms are generally peaceful and can coexist with other non-aggressive tank inhabitants. They are slow-moving and spend much of their time grazing on surfaces in search of food. Their peaceful nature makes them suitable for reef tanks, provided their dietary needs are met.

While they are not aggressive, they can be inadvertently harmful to corals if they multiply excessively, as they may cover coral surfaces and block light. Monitoring their population is important to prevent potential issues.

Health and Common Issues

In captivity, Marine Blue Flatworms can be sensitive to poor water quality and sudden changes in their environment. Ensuring consistent water parameters and a stable environment is key to their health. Regular monitoring and maintenance of water quality are essential to prevent stress and disease.

When selecting a Marine Blue Flatworm, look for individuals that are active and free from visible signs of disease or damage. A healthy flatworm will have a vibrant color and smooth, intact body.

Habitat

Marine Blue Flatworms are naturally found in shallow reef environments, often inhabiting areas rich in live rock and coral rubble. They prefer stable, warm waters with moderate flow, allowing them to graze effectively while remaining protected from strong currents.

Their distribution spans various tropical and subtropical regions, where they contribute to the ecological balance by consuming detritus and aiding in nutrient cycling.
