Water Conditions for Taiwan Moss

Taiwan moss is found in the fast-moving freshwater river banks. It thrives best when the plant is fully submerged under the water.

Moisture plays a critical role in the growth of the plant.

Rising water temperature reduces the growth causing it to slow down the expansion.

Change in the water temperature may affect the growth rate, but still, the plant will grow at a decent pace and occupy an area in the tank.

However, the Taiwan moss is quite hardy compared to similar aquarium plants. It can sustain in a warm as well as a cold water tank.
