So I've just put a harlequin in the tank, in a fish trap for now.
All my asterina have come out in the masses and started climbing the glass as if they know they are about to be eaten,
I'm guessing they can sense the shrimp

Weirdly.... Yes...

I have seen asterina come out in droves and run up the glass when they come out to hunt as well.

The shrimp hunts by smell. Suppose the stars can sense them as well
