General information

The Purple Sea Rod, scientifically known as Muricea muricata, is a species of gorgonian coral that is popular among reef aquarium enthusiasts for its striking purple coloration and intricate branching structure. This species is part of the family Plexauridae and is native to the tropical waters of the Eastern Pacific Ocean. The Purple Sea Rod is a filter feeder, capturing plankton and organic matter from the water column with its tiny polyps.

Care

Muricea muricata requires moderate to strong water flow and low to moderate lighting conditions in the aquarium to mimic its natural habitat. It is important to maintain stable water quality, with specific attention to calcium and alkalinity levels, to support the coral's growth. Supplemental feeding with planktonic foods can benefit the Purple Sea Rod, especially in systems where natural food sources are scarce.

Reproduction

Like many gorgonians, the Purple Sea Rod reproduces both sexually and asexually. Sexual reproduction occurs through the release of gametes into the water column, leading to external fertilization. Asexual reproduction happens through fragmentation, where pieces of the coral break off and attach to the substrate to form new colonies. This method is often used by aquarists to propagate the species in captivity.

Symbiosis

While Muricea muricata does not have the same level of symbiotic relationships as some other marine organisms, it does provide habitat and shelter for a variety of small marine creatures, such as brittle stars and small crustaceans, which can hide among its branches.

Habitat

The natural habitat of the Purple Sea Rod is typically on rocky substrates or coral reefs, where it can be found at various depths. It is often seen extending from vertical walls or overhangs, taking advantage of the water flow for feeding.
