  3. Browning Leaves – The leaves on java moss can begin to brown whenever they are deprived of clean water, light or nutrients. In order to prevent the death of your java moss, you should add some fish-friendly fertilizer to your tank. This will help to ensure that the growth of algae remains within your control. Optimizing the lighting to a moderate level will also help to prevent the growth of algae within the tank.
  4. Overgrowing – you should trim your java moss regularly in order to prevent it from overwhelming the tank. This not only provides a cleaner aesthetic but it promotes healthy growth in the plant itself as it allows its stems to have access to an appropriate level of lighting.
