Common name: varicose Phyllidia

General information

Phyllidia varicosa, commonly known as the Varicose Phyllidia or Varicose wart slug, is a striking species of nudibranch, a group of soft-bodied, marine gastropod mollusks. This species is easily recognizable by its vibrant coloration and distinctive wart-like tubercles on its dorsum. The bright colors serve as a warning to potential predators about the toxic nature of the chemicals it contains, which it derives from its sponge diet.

Care

In the home aquarium, Phyllidia varicosa requires a well-established system with plenty of live rock and a stable environment. They are not recommended for beginners due to their specific dietary needs, feeding exclusively on certain sponges that can be difficult to provide in captivity. Stable water quality and parameters are crucial for their health.

Reproduction

Reproduction in Phyllidia varicosa involves laying a ribbon of eggs on the substrate. In the aquarium, breeding is rare and raising the larvae to adulthood is challenging due to their complex life cycle and specific dietary requirements.

Habitat

Phyllidia varicosa is found in the tropical Indo-Pacific region, typically on coral reefs or rocky substrates where its food sources, various sponges, are abundant. They are usually seen at depths ranging from shallow waters to about 30 meters.
