yeah, sorry for the confusion. I have had "stupid weeping moss" in mind hunting this for a while.
This is the willow moss (fontinalis antipyretica) which i find to be one of the largest and slowest to grow. it also does not scale well in small tanks and not as popular as say xmas, taiwan or peacock varieties.IMHO, it only looks good when trimmed short. otherwise it gets leggy and looks less bushy if grown out.
