Aiptasia Inside Torch Coral?

[jisyokputih]

Hi all,

Just wanna make sure if this pulsing thing inside of my torch coral is aiptasia?
I think it's stinging the torch's tentacle.

First pic looks like it’s a fan worm, which may irritate, but won’t sting.
Second pic, it looks like a nudibranch, depending on the type, it would either be harmful or not. Typically, nudis specialize in in a single type of organism, i.e. sponges, algae, zoas etc

Have you noticed it moving around or has it been in the same location?
Try to blast it off with a turkey baster, see if that dislodges it.

Hopefully someone else can chime in with a better perspective

Based on the video it looks like a barnacle, surrounded by mesenterial filaments(guts) from the coral, most likely a response to the irritation.
