The only way to propagate this plant with any success is to divide the plant in clumps. Simply hold the plant and break away pieces with your hands or by using scissors and then attach them to a rock or wood with fishing line or a rubber band until they attach themselves with their delicate root system. In some aquariums, Java Moss is used as a floating plant especially in fry rearing tanks where the young fish need extra cover.
This is a fairly undemanding plant as long as it is given bright lighting, patience is required to grow this plant as it is very slow growing. It is used extensively in planted tanks to create aquascape as it can be attached to any surface, even filter intake pipes.It’s nearly impossible to grow nicely in harder and alkaline waters. Such waters cause brownish colour, but the plant will grow anyway.Attach this plant to some rock and add some fertilizer for acclimatization. Good lighting is necessary.

How does Java moss look like?
Answer: It has small roots and is usually used to create carpets in the aquarium. Depending on lighting and pH, it can be green (good conditions) or brown (bad water conditions). However, brown colour doesn’t mean that the plant is dead.
