What're these poking out the sides?

Saw something that looked like two antenna or tentacles sticking out between two zoas... Any idea if these are part of the zoa, or am i looking at a hitchhiker?

Not part of the zoa. Do they retract when you touch them?

 

[legrunt]

Nope... Like two blades of grass. Flicked at them, no reaction...

Some sort of algae probably. Pick them out with a tweezers.
