Green shoot-like plant ID?

[imbob95]

Can anyone ID this algae/plant ? Crab and snails don’t touch it… just wondering if it’s safe for the tank?

Neomeris algae - typically harmless, but sometimes it can be invasive. Urchins reportedly eat it if it gets out of hand.

Maybe Caulerpa prolifera? I don't know for sure though

Thank you!!
