Common name: Phyllidia exquisita

General information

Phyllidia exquisita is a species of colorful sea slug, a nudibranch, belonging to the family Phyllidiidae. Known for its striking appearance, it features a vibrant pattern of black lines and yellow to orange tubercles on its dorsum. This nudibranch is not only admired for its beauty but also for its chemical defenses, which it derives from its diet of sponges.

Care

Caring for Phyllidia exquisita in a reef aquarium requires attention to water quality and tank conditions. They are sensitive to high levels of nitrates and phosphates, so maintaining pristine water is crucial. As specialist feeders, they require a diet of specific sponges found in their natural habitat, which can be challenging to provide in captivity. Therefore, they are recommended for experienced hobbyists who can meet their dietary needs.

Reproduction

Like many nudibranchs, Phyllidia exquisita is a hermaphrodite, possessing both male and female reproductive organs. They can engage in reciprocal mating, where both individuals exchange sperm to fertilize their eggs. The eggs are laid in a spiral ribbon and will hatch into free-swimming larvae before settling down and transforming into the adult form.

Habitat

Phyllidia exquisita is typically found in the tropical Indo-Pacific region, on coral reefs and rocky substrates. They are often observed at depths ranging from shallow waters to about 30 meters, where they feed on specific species of sponges.
