What kind of nem is this

[Bleedmichigan]

So I was given a few nems from a guy breaking down his tank. Two bubble tips, and one mystery nem. Looks like a rainbow tip but tentacles don’t bubble like I would expect for a bubble tip. Is it a long tentacle?

backstory.
meh was breaking down his tank. Couldn’t find the nems. This guy was wedged into a piece of rock. Looked small when I set him in my qt tank. Now is between 4-6 inches when open.

Bta? Does it bubble?

Not that I have seen. But it seems happy. It moves sometimes but not often.

+1 my BTAs seem to bubble only when they're hungry. And only rarely then
