notes - this is a very beautiful, hardy, fast growing, and very rewarding aquarium plant that will be the best addition to almost any home aquarium setup. due to its low care requirements it will grow green in the worst of conditions. this plant has many advantages including it being one of this plants that will help with ammonia issues, there have been studies with java moss, and it took 2 weeks for a small female betta to produce .25 ppm ammonia in a 1 liter tank. from my own experience my fish love to swim through the tangled up moss, this plant has helped my fry survive to adulthood as they retreated in it as soon as the bigger fish came by.
I have found when Java Moss is left to float in the tank it tends to tangle in the filter or attach to everything in the tank. It is easier to control when attached to wood, rocks or other objects. Just my thoughts.
