Anubias is a genus of aquatic plants commonly used in aquariums and terrariums. They are known for their slow growth and hardy nature, making them popular choices for aquascaping and low-maintenance aquariums. Anubias species can be attached to rocks, driftwood, or other surfaces in the aquarium and can grow both underwater and partially emerged from the water. They are also known for their ability to absorb excess nutrients from the water, helping to maintain water quality.
