Common name: Blue nudibranch

General information

The Painted Phyllidia, scientifically known as Phyllidia picta, is a vibrant and colorful nudibranch, a type of sea slug. This species is part of the Phyllidiidae family and is known for its striking appearance, which includes a pattern of black lines and yellow to orange tubercles on a blue to purple background. Nudibranchs like Phyllidia picta are often sought after by underwater photographers and marine enthusiasts for their unique beauty.

Care

Phyllidia picta requires a specialized aquarium setup that replicates their natural environment. They are sensitive to water quality and require stable conditions with excellent water filtration. As they feed on specific sponges, it is crucial to ensure that their dietary needs are met, which can be challenging in a home aquarium. They are best suited for experienced aquarists who can cater to their specific requirements.

Reproduction

Nudibranchs, including Phyllidia picta, are hermaphrodites, possessing both male and female reproductive organs. They can lay masses of eggs, which hatch into free-swimming larvae. These larvae eventually settle and metamorphose into the adult form. Reproduction in captivity is rare and requires precise conditions that are difficult to achieve in home aquariums.

Habitat

Phyllidia picta is found in the tropical Indo-Pacific region, typically on coral reefs or rocky substrates. They are benthic creatures, meaning they live on the bottom of the ocean, often at depths ranging from shallow waters to about 30 meters deep. Their presence indicates a healthy reef environment with an abundance of their preferred sponge prey.
