Common name: Collingwood's Chromodoris

General information

Goniobranchus collingwoodi, commonly known as Collingwood's Chromodoris, is a striking species of nudibranch, a group of soft-bodied, marine gastropod mollusks. This species is known for its vibrant coloration, which includes a white body with a pattern of pink and purple lines and spots, and a bright orange border. It is a popular subject for underwater photographers and a fascinating addition to the marine aquarium.

Care

Collingwood's Chromodoris requires a specialized aquarium setup that replicates its natural environment. The tank should contain plenty of live rock and a well-established community of microfauna to provide a natural source of food. Stable water quality, with excellent filtration and regular water changes, is crucial for the health of this nudibranch. They are sensitive to high levels of nitrates and copper-based medications.

Reproduction

Like many nudibranchs, Goniobranchus collingwoodi is a hermaphrodite, possessing both male and female reproductive organs. They can lay ribbons of eggs, which hatch into free-swimming larvae. These larvae eventually settle and metamorphose into the adult form. Breeding them in captivity is challenging due to their complex life cycle and specific dietary requirements.

Habitat

Goniobranchus collingwoodi is found in the Indo-Pacific region, particularly in areas with coral reefs and rocky substrates. They are benthic creatures, often seen crawling on the substrate or on the surfaces of rocks and corals in search of sponges and other small organisms to feed on.
