They're spreading - What are they?

[jroescher]

They came in on a mushroom rock and are now starting to spread around. Each 'polyp' is about 1/4".

look like clove polyps to me...nice ...

[FireEater]

Yep, now is the time to take the rock out and toothbrush the weeds that will take over your tank quickly.

Clove Polyps=Weeds ....not in my book...

They are not clove polyps (I think). Kill them as fast as you can. Smother them, poison them, or what ever. Those brown butt ugly little things will take over. -SoLiD
