If fish eat aquatic plants, they can be isolated or raised with some hard grass to prevent them from being eaten. Many fish don't take the initiative to eat aquatic plants, unless they are hungry. As long as there is enough food in the feeding process, the fish are not interested in aquatic plants. However, some fish will eat aquatic plants exclusively. This kind of fish must not be raised in grass tanks, otherwise it will seriously damage the environment. It is best to raise some omnivorous fish with small size.
