White thing in octopus coral?

[Trueruby]

Hello Everyone,
Since, 15 days I have realized that there is something white in my octopus coral and its always in samelocation. Whenever I try to take coral to check, it closes it self so I dont see what it is. I got a really nice video of it.
Does anyone knows what it is?
Thanks in advance

It’s really hard to tell from that pic and I am unable to see the video........ look up mesenterial filaments and see if it looks similar to what you are seeing.
