I would say that if it thinks it is food, it would.
I 'tried' to put a peppermint shrimp in my GSM/with abundant rose anemones tank, and I made the mistake to let the shrimp go from the top of the water column after acclimation.
Well, the big female GSM grabbed it, and since it was too big, went right into her big rose anemone, held it in her mouth for a couple seconds, then spat the shrimp out to the anemone....
Well..the anemone then just thought it was food, and closed down...on a nice $5.00 meal.
Best,
