You will get 1 loose portion (2 inches in diameter) of green (never brown) Java Moss in a 4 oz cup as can be seen in the second picture. Java moss will grow in a variety of water conditions (pH 6.0-8.), and lighting conditions (moderate to intense). It makes a great addition to shrimp tanks, and makes a perfect hiding place for newborn live bearers. It can be left free floating in your aquarium or attach it to driftwood with fishing line to add a distinct look to your aquarium.
