coral excretion?

[snowlynx]

I notice every new coral I introduce or touch to move elsewhere
produces this fine thin clear thread. Is this some excretion or
toxic chemical warfare?

Your skin has oils that they don't like...

Most corals can secret a slime that it uses to protect itself when disturbed. Try being gentler and wear non powdered nitril gloves when you come in direct contact with coral.

Yes. Just protecting itself.
