Swimming anemone?

[pufferPandimonium]

Does anyone know what this might be it was in some chaeto I thought is was some kind of pest anemone but when I went to get it out one swam of in a jellyfish kind of swimming. Any help would be appreciated I’m not having much luck with google.

I'm pretty sure it's a swimming species of aiptasia. There have been a few other posts about them on this forum.

Weird -- no idea but Web search caused me to find this interesting:

Swimming Anemone

*one of the pictures looks similar (to me),,, and native environment feels at least plausible (to me)

Yeah, there are a few different species of nems that swim - the most common in the hobby is Boloceroides mcmurrichi, so that's the most likely.

Looks like it may be a very small Swimming Anemone, Boloceroides mcmurrichi. For a fairly similarly sized specimen to compare with:

Yeah I was looking at that one swimming anemone thinking it might be it but its tentacles are rounded at the ends and those seem all pointy maybe as it’s smaller? The top one on the biodiversity of Singapore looks real close. Looks like it’s something to remove. I don’t need anemones swimming around stinging coral. Thanks for the reply’s!

Yeah they can be problematic, but I think they're pretty neat! If I ever come across them I'm doing a dedicated nano just to watch them swim.
