Anubias is a plant that can grow underwater in aquariums. It is kind of like a big green leaf with little roots growing out of it.
To make sure Anubias stays healthy, you need to put it in water that has good quality and the right temperature. This will help it grow big and strong.
Additionally, Anubias doesn't need a lot of sunlight to grow, so you don't have to worry about putting it near a window.
When you take care of Anubias, it will also help keep your aquarium balanced and clean. This means that your fish and other aquatic animals will be happy and healthy too!
