Somewhat new, what is this tentacley thing?

[jamesdem1123]

Hi,

TLDR: is this a long tentacle anemone, bobbit worm, or something else?

Video link

I started with a 14 gallon then moved to a 37 with a bunch more rock so I could get a dragonet in the future. Some rock was from 14, some new base, and some store bought wet/live.

I saw this thing in the video anove the other day and not sure what it is? At first I thought bobbit, but the tentacles are longer and more plentiful. Is it a long tentacle anemone? I did just add a rbta earlier that was in an anemone tank

Thanks!

aiptasia. Pest anemone. Unless you are breeding nudibranch.

+1. Aptasia.

I usually make kelkwasser into a thick paste (like tooth paste consistency) and put a glob completely over any aptasia I see. Just leave the blob, it will eventually mix into the water and go away, and the aptasia it’s on will die

good luck my friend!

Looks like it’s in a good location to entomb it for eternity with some putty.
