easiest mosses to maintain?

[genocidex]

im looking for a moss that wont grow very long, and will hopefully stay put on my rock. it would be ideal if it would stop growning at the rock's edged but i know thats a pipe dream lol.

was looking at flame and xmas mosses, do they grow long or out?

im currently loathing java moss and want something to help my RCS relax. after seeing how lost they are without moss i figured i would give them something.... might not need it after i add the micro swords.

Java moss and willow moss grow easy and fast. Both will require regular attention to stay in shape. If you want to cover a rock and you got enough light get some plastic netting and riccia.
