We might be going to the shop tomorrow that sells them. I'm not after tham for the benefits they bring, I was wondering whether its just a way of selling Java moss. I can't get it anywhere else.
They are the green algae(?) Cladophora aegagropila.I have 2 and they seem to soak up dirt like a sponge. If you don't turn them on a regular basis they will flatten out.
i was nervous of using them at first as i like to see what i'm getting before i buy but when i recieved the parcel all the contents were perfect. nothing dead and much bigger plants than you get for the same price in the LFS.
None of the lfs or lps around here have java moss. I do have 2 moss balls though. They're pretty cool looking. I don't know that they really are beneficial, other than being a plant, but they do add interest. I got mine from a fellow off ebay. As a matter of fact, I've gotten most of my plants from him. (Very good plants and price.)
