Green Tube On Lr?

[Benji]

Hey everyone. We just moved things over to a newer bigger tank ( I'll make a build thread soon), but I noticed these bright green tubes on one of the rocks? Anyone know what it is?

Vermetids aka tube snails? I have many of these but mine are more of a white colour.

I haven't touched them but they look squishy.
