Help identifying

[James butchart]

Hi guys

I've starting getting corals for my tank.
I got xenia to start because I love the movement. There really doing well but I've noticed something beside them on the bit of live rock they came on. I'm hoping someone help identifying it.
Thanks.

Hi thanks for the reply.
I didn't know what it was. I just looked at a YouTube video of them and I've found another small one that looks the same in the video. Free coral woohoo.
