Pro tips
Hard-won lessons from the tank.
The definitive 'underwater bonsai' moss — attach to the upper branches of a tree-shaped driftwood and let it droop. Looks identical to a weeping willow. Trim only the dangling ends every 4–6 weeks to maintain shape; never trim the upper attachment.

Algae
Algae issues
Drooping fronds can trap detritus and develop algae if flow is too low.
Common mistakes
Common mistakes
1) Attaching low — drooping habit can't develop. 2) Low flow — detritus and BBA accumulate.
How to care for it
The practical routine, read top to bottom.
Tying / attachment
Attach to high points on driftwood or vertical scape — fronds will droop downward from attachment point.
Tank setup
Medium-high light. CO₂ improves the drooping habit significantly. Decent flow prevents detritus collection in the canopy.
