You have two identical posts, remove one and I bet people will answer.

Are you feeding it? What are the growing conditions; full sun/part/shade? How tall were the divisions that you initially planted? The more info you provide, the better an answer you'll receive =)

My internet has been playing up I have pics but can't post for some reason. Not feeding it but haven't fed other either and they are up to six foot approx. it's on north facing wall I live in uk on top of mountain so pretty windy at times but it's sheltered with a wall. I initially put them in three years ago sept time. My rabbit ate some of the aurea but then in spring it bounced back but only to height if a foot. It looks so silly between the others and I'm not sure what to do.

I'm posting off my phone so any tips to get pics up to show you all great fully received.

No replies but thought i would update anyway. A famous tv gardener has identified that my bamboo could have been incorrectly labelled and is actually the Pleioblastus. Having seen picture of it. This is exactly what I have. Not happy as it was labelled incorrectly. I know have to try and get it out! Argh
