[skools717]

http://www.duboisi.com/diy/BNdiygrotto/bndiygrotto.htm

and i wanted to have a plant growing on the rocks to look more natural

so im looking for a plant that doesnt need a whole lotta light and grows without substrate, would java moss or something similar work, and if needed i know how to do the DIY Co2 thing

What kind of fish do you plan on keeping in this new setup?

 

[carolinyens]

Anacharis will be one that you dont need to bother with. Or guppy grass
Added: ok these arent gonna go too well on rocks. sorry about that. Look under the plant websites thread and just take a gander at those sites. Theres bound to be at least one that'll get you what you want.

java moss, java fern, or anubias are good lowlight plants that would work.

Java moss can grow floating or tethered to a rock with no issues, nor need of substrate.

Water sprite would work

yup. java fern/moss.

 

[abarilot]

My java fern and anubias are growing well attached to my drift wood so should work for rock as well

moss balls and x-mas moss also. moss balls can get kinda messy but xmas moss can grow on plastic grids like the use for knitting and can create a whole backdrop for ya.
