Broken or ?

[Orddie]

This is the second time in two weeks a piece of this birds nest has “broken” off like this. To my knowledge, I did not bump it or touch it. Any reason for concern? AI says it’s natural.

I have had fish that broke stuff if they got spooked, but usually these things happened to me during siphon work in the gravel. Many sps colonies in aquarium are insanely fragile, ime.
