Common name: Red Algae

General information

Gracilaria parvispora, commonly known as Red Algae, Ogo, or Limu Manauea, is a species of red macroalgae that is highly valued in the reefkeeping hobby for its numerous benefits. This algae is not only sought after for its natural beauty and ability to add a diverse range of colors to the aquarium, but also for its role in nutrient export and as a natural food source for herbivorous fish and invertebrates.

Care

Caring for Gracilaria parvispora in a home aquarium requires moderate lighting and good water flow to mimic its natural habitat. It can be easily attached to live rock or placed in a refugium where it can grow without being disturbed by fish. Regular pruning is recommended to maintain its shape and promote healthy growth. It's important to monitor nutrient levels, as this algae can help control nitrates and phosphates when kept in proper conditions.

Symbiosis

While Gracilaria parvispora does not have specific symbiotic relationships like those seen in coral or anemone species, it does provide a habitat and food source for a variety of small invertebrates and fish. It can be particularly beneficial in tanks with tangs and other herbivorous fish that graze on algae.

Habitat

Gracilaria parvispora is found in shallow, warm waters where it attaches to hard substrates or grows among other seaweeds. It is commonly found in the Indo-Pacific region, thriving in areas with ample light and water movement.
