Growth on coral skeleton. Tissue shrinkage.

[Andrewrckt]

Hello,

I noticed one of my corals looking a little sad today. I took a closer look at it and found some white growth on the skeleton. Some have a tube like structure, but it doesn’t look calcified or hard. I took a couple pictures of it. Any ideas of what it is/ how to save this guy. It has been looking good for months but noticed some issue with it today.

You can scrap off the white tubes if its irritating your coral. What are your parameters?
