Common name: rose Phyllidiella

General information

The Rosy Nudibranch, scientifically known as Phyllidiella rosans, is a striking sea slug that belongs to the family Phyllidiidae. These nudibranchs are known for their vibrant pink to purple coloration with black ridges and yellow accents, making them a visually appealing addition to any reef aquarium. They are not only admired for their beauty but also for their role in the ecosystem as they feed on sponges, which helps control sponge populations in the reef.

Care

Caring for Phyllidiella rosans requires a well-established reef aquarium with a stable environment. They are sensitive to water quality and require pristine conditions with low nitrate levels. It's important to provide them with a supply of their natural food source, sponges, to ensure their health and longevity in captivity. Due to their specific dietary needs, they may not be suitable for beginners.

Reproduction

Reproduction in Phyllidiella rosans involves laying spiral ribbons of eggs on the substrate or on sponges. In the aquarium setting, successful breeding is rare, and the larvae require specialized care to reach maturity.

Habitat

Phyllidiella rosans is typically found in the Indo-Pacific region, from the Red Sea to the central Pacific. They inhabit coral reefs and prefer to dwell on or near their food source, sponges. They can be found at various depths, often ranging from shallow waters to deeper reef slopes.
