Anemone? Aiptasia?

[nosferatu_mysids]

Hey everyone, I was wondering if anyone could identify this species. It’s currently 1-2 mm in size and was found in saltwater taken from the Indian river for analytical testing.

It appears to be eating (and stinging) artemia, and is growing quickly in 20% saltwater

Thank you!

Def. don't think it's Aiptasia...
