ID: This anemone is from the family Aiptasiidae, and as of 2023 has the published name of Bellactis Lux. The TBS Lightbulb nem come in shades of brown, sometimes beige, sometimes a greenish hue and rarely a translucent yellow. It sometimes has stringy tentacles much like a bubble tip doesn't...

They have it defined in the aptasia family. It's also under their hitchhiker tag.
Their pictures look different tha typical aptasia from a visual point if view.
But on the flip side thing looks ugly as heck To me Majanos look way better imo (though I still doubt and one would intentionally add one of these to a tank beyond a scientific purpose or maybe if they are breeding bergs.). I definitely wouldn't add anything remotely close to the aptasia family willing to my tanks.
So calling it aptasia isn't wrong. Lol more fancy aptasia???
