There are wonderful grassy plants in the aquarium that can make a beautiful carpet of grass in your aquarium, two of my favorites are Najas and Zosterella.NajasIt has spiny leaves and is called the spiny naiad. Najas can grow extremely quickly in the aquarium and are very useful as a breeding plant.ZosterellaZosterella is similar in appearance to the Potamogeton and Najas. If there’s one thing I can say about Zosterella dubia, it grows. This is one of the fastest growing and hardiest plants I’ve had the pleasure of growing. The plants also bloom easily. Of course the different plants requirements will vary, but in general I’ve found all three of these types of grassy looking plants can grow very well in the aquarium.
