Anemone ID question (no pics)

[ClamIAm]

I was at a store today and they had an unusual anemone. It was almost clear but had a slight greenish tint to it. The tentacles had small protrustions coming from them. They had it labelled as a "White Tentacled Anemone" but weren't sure what it really was. I know this sounds pretty vague, but I've never seen anything like it before and so I'm thinking it may be distinct enough to ID. The closest pictures I've been able to get to what it looks like are hell's fire anemones, but they aren't the same and the guy at the store said he hadn't been stung by it nor did it eat anything in the tank so I don't think it is this.

can easily be a bleached green BTA without pictures it might be a bit hard to tell

I'm sure pics would be quite helpful, but unfortunately I didn't have a camera on me and the store is a bit far from where I live. Another factor that may help is it seemed to like burying its foot in the sand.

can be M.doreensis long tenacle anemone if it bury its foot down.
