What's under my acro?

[minus9]

I have something living under my acro frag and I can't seem to find any info on it? Where the tentacles are most prevalent, there's little or no growth. I dipped in revive, but it continues to live.
Any thoughts?

If it seems to be irritating your bonsai you can glue or epoxy to smother it.

Sort of looks hydroids

I'm gonna glue it in and see what happens. I noticed all the new growth in the front and not the back, which made me look closer. It's not hydroids, but could be an anemone-type critter. It comes out more at night. I'll have to take a pic tonight before I glue it in.
Thanks for the help everyone!

Your Bonsai looks healthy, IMO. I wouldn't worry too much unless health starts to go downhill.

Thanks, rfgonzo, I'm hoping it will encrust over the LR and cover it up in the process.

rfgonzo is right. i personally would glue it. it would just be a eye sore overtime i looked at it
