Common name: red-netted goniobranchus

General information

The Dyed Nudibranch, scientifically known as Goniobranchus tinctorius, is a colorful and striking sea slug found in the Indo-Pacific region. This species is part of the Chromodorididae family, which is known for its vibrant and diverse color patterns. The Dyed Nudibranch is particularly admired for its intricate pattern of blue, black, and yellow hues, making it a visually appealing addition to any reef aquarium.

Care

Goniobranchus tinctorius requires a specialized aquarium setup that mimics its natural environment. They are sensitive to water quality and require stable conditions with excellent water filtration. As they are not photosynthetic, they need to be fed a diet of sponges, which can be challenging to provide in captivity. It's essential to research and ensure a sustainable food source before adding them to your tank.

Reproduction

Nudibranchs, including Goniobranchus tinctorius, 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. Breeding them in captivity is complex and rarely achieved by hobbyists due to the difficulty in providing the appropriate larval food sources.

Symbiosis

While not known for any specific symbiotic relationships like those seen in clownfish and anemones, nudibranchs play a role in the reef ecosystem by controlling sponge populations, which can otherwise overgrow and smother corals.

Habitat

Goniobranchus tinctorius is typically found in the tropical waters of the Indo-Pacific, from the Red Sea to South Africa and east to the central Pacific. They inhabit coral reefs and rocky substrates, often seen crawling on or near their food source, sponges.
