thanks cruise control and DOM ,

i dun really know what it the real name of the moss, but in singapore they call it mini moss. it looks really similar to x-moss.this is my first time trying the moss too.

hi cruise control,
i only use lava rock in this setup. the moss on the base is being tied to a small broken rocks that i manage to collect for the past 1 month. and the one hang on the rock, i didn't tie it. just place it on top of it..once the root grows they just attach to the rock...need to be careful when doing water changes...but it only takes 1 months before the moss start to attach to the rock ...
just worried about algae growing ...
