Common name: Gracilaria tikvahiae

General information

Gracilaria tikvahiae, commonly known as Curly Sea Moss or Red Algae, is a species of red macroalgae that is not only important in the wild but also popular in the saltwater aquarium trade. This species is appreciated for its ornamental value, its role in nutrient export, and as a natural food source for herbivorous marine animals.

Care

Curly Sea Moss is relatively easy to grow in a reef aquarium, provided it receives moderate to high lighting and some water flow. It can absorb excess nutrients like nitrates and phosphates from the water, which helps to maintain water quality and reduce the likelihood of nuisance algae outbreaks. It can be attached to live rock or left free-floating.

Symbiosis

While not involved in the classic symbiotic relationships seen with corals and fish, Gracilaria tikvahiae does play a role in the ecosystem of a reef tank. It provides a microhabitat for small invertebrates and can be a food source for herbivorous fish and invertebrates, fostering a more natural environment.

Habitat

In the wild, Gracilaria tikvahiae is found in a variety of marine environments, from brackish waters to coral reefs. It is adaptable to a range of conditions but typically thrives in areas with good water movement and plenty of light.
