Genus

Common name: Green Felt Algae

Scientific name: Avrainvillea

Avrainvillea is a genus of green macroalgae commonly found in reef aquariums, known for its felt-like appearance and dark green coloration. It's a benthic algae, often growing on substrate or live rock, and can be a good nutrient exporter. It's also known as Turtle Grass, though it's not a true seagrass. Avrainvillea species can be beneficial in a tank for their ability to absorb excess nutrients, but they may require trimming to prevent overgrowth. They are generally hardy and can thrive in a range of lighting conditions, making them suitable for various tank setups.
