Common name: Dwarf Red Algae

General information

Gelidium pusillum, commonly known as Dwarf Red Algae, is a species of red algae that is well-regarded in the reefkeeping community for its potential to add a splash of color and natural diversity to the aquarium. This species is part of the Rhodophyta phylum and is known for its small, bushy fronds that exhibit a vibrant red hue. It is not only aesthetically pleasing but also plays a role in nutrient export, as it can absorb excess nutrients like nitrates and phosphates from the water column.

Care

Dwarf Red Algae is relatively easy to maintain in a reef aquarium, provided that it receives moderate lighting and water flow. It is adaptable to a range of lighting conditions but thrives best under moderate to high lighting. It is important to ensure that the water quality is maintained, as Gelidium pusillum can be sensitive to high levels of pollutants. Regular water changes and efficient filtration can help maintain the appropriate water conditions.

Symbiosis

While not known for hosting or forming direct symbiotic relationships with marine animals, Gelidium pusillum can contribute to the overall health of the aquarium by providing a natural food source for herbivorous fish and invertebrates. Its presence can also enhance the habitat complexity, offering shelter and grazing areas for small organisms.

Habitat

Gelidium pusillum is found in a variety of marine environments, often attached to rocks or other hard substrates in the intertidal to subtidal zones. It is a versatile species that can adapt to different levels of light and water movement, making it a suitable candidate for various aquarium setups.
