Common name: Red-spotted Nudibranch

General Information

The Red-spotted Nudibranch, scientifically known as Vayssierea felis, is a small and intriguing species of sea slug belonging to the family Okadaiidae. It is often found in shallow waters and tide pools, making it an interesting addition to marine aquariums for those who appreciate the diversity of marine life. This nudibranch is particularly known for its distinctive red spots against a translucent red or orange body, making it a visually appealing specimen.

Although not commonly found in the aquarium trade, Vayssierea felis can be a fascinating subject for marine enthusiasts interested in nudibranchs' unique lifestyles and ecological roles. Its presence in aquariums can contribute to understanding the complex interactions within marine ecosystems, especially its role in controlling spirorbid worm populations.

Care

Caring for the Red-spotted Nudibranch requires attention to detail and an understanding of its specific needs. It thrives in tanks that mimic its natural habitat, with rocky substrates and plenty of hiding spots. As a delicate species, it requires stable water conditions and should not be housed with aggressive tank mates.

Due to its specialized diet, ensuring a sufficient supply of spirorbid worms is crucial for its survival. This can pose a challenge in captivity, as these worms are not always abundant in home aquariums.

Diet and Feeding

Vayssierea felis is a carnivorous species that feeds exclusively on spirorbid worms. In the wild, it plays a role in controlling these worm populations, which can be beneficial in aquariums where spirorbid worms are considered pests.

Providing a consistent supply of spirorbid worms is essential, and hobbyists may need to cultivate these worms separately to ensure their nudibranchs have enough to eat. Feeding frequency depends on the availability of worms, but regular monitoring is necessary to ensure the nudibranch receives adequate nutrition.

Behavior and Compatibility

The Red-spotted Nudibranch is generally peaceful and poses no threat to other marine life. However, its small size and specific dietary needs mean it should be housed with care. It is best kept in species-specific tanks or with other peaceful invertebrates that do not compete for the same food sources.

Health and Common Issues

Vayssierea felis is a delicate species that requires stable water conditions and a consistent food supply. It is susceptible to changes in water quality and should be monitored closely for signs of stress or malnutrition.

Selecting a healthy specimen involves looking for active individuals with intact coloration and body structure. Avoid nudibranchs that appear lethargic or have visible damage.

Routine care involves maintaining optimal water quality and ensuring a steady supply of spirorbid worms. Regular water changes and monitoring can help prevent common issues related to water quality and nutrition.

Habitat

Vayssierea felis is naturally found in shallow, rocky tide pools and coastal waters. It prefers environments with ample hiding spots and rocky substrates, where it can find its primary food source, spirorbid worms. Replicating these conditions in captivity can enhance its well-being and longevity.
