Hi I just bought a mushroom rock from the LFS. the rock has alittle bit of hairalgae and a plant that I cant seem to ID. It looks kinda like a Saw Blade.. Please look at the pictures and letme know if you have any ideas. Thanks, Lance

Looks like feather caulerpa. Any herbivores will make that a quick snack.

I would agree that its probably some type of caulerpa, give it a little while to develop. right now it just looks like caulerpa runners and roots to me without the leaves developed.
