Care & Growing Guide

Caring for Weeping Moss isn’t overly complicated, but knowing a few key details can go a long way in ensuring its successful growth.

Tank Requirements

Weeping Moss is quite forgiving and adapts well to various tank setups. For optimal growth, try to mimic its natural habitat. Moderate water flow, a stable environment, and plenty of surfaces for the moss to attach to (like rocks or driftwood) are all beneficial.

Tank Size

Thanks to its compact growth, Weeping Moss can fit into tanks of virtually any size. Even in a small 5-gallon tank, it can be an eye-catching feature.

Water Parameters

This moss prefers slightly acidic to neutral water conditions with a pH range of 6.0 to 7.5. The temperature should be kept between 20 to 28°C. However, Weeping Moss can tolerate a wider range if changes are gradual.


Weeping Moss absorbs nutrients directly from the water. If you keep a low-stock tank or your water is relatively clean, consider using a high-quality liquid fertilizer to ensure it gets necessary nutrients.


Weeping Moss doesn’t necessarily require additional CO2. However, if you’re aiming for more vigorous growth, CO2 supplementation can indeed help.


Weeping Moss thrives in low to medium light conditions. Avoid intense light, which can lead to algae growth and might damage the plant.


Substrate choice isn’t a big concern for Weeping Moss since it doesn’t have roots and primarily attaches to hardscape. You can pick any substrate you like for the rest of your tank.

Trimming & Pruning

Regular trimming will keep your Weeping Moss looking tidy. Don’t shy away from cutting it back; this moss handles trimming well and will regrow more robustly.

Tips to Make Your Weeping Moss Grow Faster

  • Keep water parameters within the ideal range.
  • Supply a balanced liquid fertilizer if necessary.
  • Consider CO2 supplementation for quicker growth.
  • Regularly trim the moss to stimulate denser growth.
