Common name: delicate spiny sea rod

General information

The Flexible Sea Rod, scientifically known as Muricea laxa, is a species of gorgonian coral that is appreciated by aquarists for its unique appearance and movement in the water current. This species is characterized by its branching, tree-like structure with a flexible skeleton made of gorgonin, which allows it to sway gracefully in the water flow. The polyps of Muricea laxa are typically extended during the day, giving the coral a fuzzy appearance, and are known for their range of colors, including shades of purple, red, and yellow.

Care

Muricea laxa requires moderate care and is suitable for intermediate-level reef keepers. It thrives in moderate to strong water flow, which helps to keep the polyps free of detritus and provides the necessary nutrients. Lighting should be moderate as well, as too intense light can cause stress to the coral. It is important to maintain stable water parameters and provide a diet of planktonic foods to supplement its nutritional needs.

Reproduction

Like many gorgonians, Muricea laxa reproduces both sexually and asexually. Sexual reproduction occurs through the release of gametes into the water column, leading to external fertilization. Asexual reproduction is achieved through fragmentation, where pieces of the coral break off and attach to the substrate to form new colonies. This can be a natural process or induced by aquarists for propagation purposes.

Habitat

Muricea laxa is found in the tropical waters of the Eastern Pacific, from the Gulf of California to Peru, including the Galapagos Islands. It typically inhabits reef slopes and rocky substrates at depths ranging from shallow waters to over 30 meters deep. In the aquarium, replicating its natural environment with appropriate water flow and substrate will support its health and growth.
