With many of our ferns and mosses originating from southeast asia, they will thrive in low to medium light setups. Many of  them grow very well in both emersed and submerged setups. Co2 is not needed but will help some of the more difficult species of moss grow slightly faster. Water flows from low to medium are preferred.

 

All mosses and ferns attach easily to rocks, wood and other hardscapes with gel super glue or string.
