How to grow Riccia as densely and compacted as possible?

[paranoid]

Hi,

Recently got myself a tank to try out Riccia, reason being of its sheer beauty with or without pearling. Have seen some very nice ones at the shop next to NA (also at NA !). If I just let the Riccia grow without any intervention, will I get the dense, compacted look?

I heard u need to peg it down when the Riccia grows to certain height. Any other methods? Anyone like to share?

Also r there different types of Riccia? Seem to be from my observation.
Thanks!

If I just let the Riccia grow without any intervention, will I get the dense, compacted look? - think so if your lighting is adequate. 3w/gallon at least.

I heard u need to peg it down when the Riccia grows to certain height. Any other methods? Anyone like to share? - go to places like NA and buy their steel meshes. throw a piece on top of any clumps that look like they're breaking loose.

Also r there different types of Riccia?- mini and normal. You can see both at System Engineering (boon keng road).

As with most plants, dense growth is stimulated by proper and regular pruning and the right conditions.
Riccia likes high light and high CO2.
