Dendro help

[JetStarheart]

One of my dendro heads split and broke apart. Just noticed it today. There was like a "blue" weak spot where its now broke. How do I keep this from affecting my other 4 heads? Is there a sealant? Or just let it be? I am currently geeding phyto/fuel mix and direct feeding bits of krill

Carefully you could seal it with Superglue gel, avoid getting any on the tissue. This "blue weak spot" has me curious as to what is going on.

. This is what I am seeing/came home to today. Thoughts? Whats going on?

Nudibranch maybe? I was just reading the latest Reef Hobbiest Magazine, and it mentioned phestilla melanobrachia as a dendro parasite.
