Will a hammerhead coral and/or bubble coral kill a seahorse?

[brm]

I have seahorses and one swam over the hammerhead coral and nothing happened but i just wanted to check and make sure.
Thanks.

all corals sting, having them with seahorses isnt advised because of their fragility, i know bubble corals are aggressive, and i thought hammers were as well, but not sure
