actually I think the green feather stuff looks kind of neat.....but like you said the green just looks out of place, and I would hate for it to get out of hand in the tank.
I do have another type which I will send pics of later that I DO want to get rid of. I haven't seen anything like it on this board. It isn't hair, isn't slime...it is green, grows like a bushy branch, not a bright green, more like a forest green.......I am baffled and it is spreading!! I will attach a pic later.
Thanks
