Personally i don't mind them. Awhile back, i was sold a rock just covered top to bottom with them. Was sold from a LFS as rock with anemone, and he even charged extra for them! Anyways, they are every where in my tank. but i plan to either get a longnose or copperbanded soon and maybe he will cut them down a little. But other than that i think they look cool, and for being a weed i have gotten compliments on them.
If ya think about it, its like somone giving your compliments on your dandilion filled lawn.
