Java Moss Tennis Ball Portion

Java Moss
This is an easy to grow moss that can be attached to a mat, rock, or driftwood.  It can also be free floating and it makes a wonderful hiding spot for female guppies and fry.  With just a little light, this plant grows and can double, triple, or even quadruple in size when left undisturbed for a month or more.  Higher lighting and fertilizers may speed up the growth of this plant, but it is unnecessary.  This plant comes from a low-medium light tank or a tub with 8-12 hours of LED light, GLA fertilizers, and liquid iron.  There may be minor brown moss that comes, but this is normal and the moss will turn green again with time.  
You are buying 1 tennis ball sized portion that will weigh at least 1.25 ounces dry to ensure proper amount.
Photos are actual plants in the picture, but will be random to plants from the tank.
