Aside from their appealing look with black and whitish-yellow stripes as the name suggests, the nerite snail readily devourers all types of algae growing on your goldfish’s tanks. A common worry among aquatic snail owners is that they are well known for their ability to rapidly reproduce and quickly overrun your aquarium, hence their label as tank ‘pests’.
