Common name: Chromodoris aspersa

General information

The Chromodoris aspersa, also known as Glossodoris aspersa, is a striking nudibranch, a type of sea slug, known for its vibrant coloration and patterns. These invertebrates are popular among marine enthusiasts for their ornate appearance, featuring a white body with black spots and yellow or orange borders. They belong to the family Chromodorididae, which includes some of the most visually appealing nudibranch species.

Care

Caring for Chromodoris aspersa in a reef aquarium requires attention to water quality and stable conditions. They are sensitive to high levels of nitrates and fluctuations in water parameters. A well-established tank with plenty of live rock and a mature biofilm is essential, as these nudibranchs feed on specific sponges found in their natural habitat. It's crucial to research and provide the correct sponge species for their diet, as they will not adapt to other food sources.

Reproduction

Chromodoris aspersa are hermaphrodites, possessing both male and female reproductive organs. They can lay spiral ribbons of eggs, which are often deposited on the substrate or on the aquarium glass. The larvae that hatch are planktonic and can be challenging to rear in captivity due to their specific dietary requirements during early development.

Habitat

Chromodoris aspersa is found in the Indo-Pacific region, particularly in tropical waters. They are benthic creatures, often seen crawling on or near coral reefs, where they feed on sponges. In the aquarium, they require a similar environment with plenty of hiding spots and surfaces to graze on.
