Those corals do not have powerful stingers that may harm the ponies by accident, which is why they are low risk
A Derasa clam gets huge (waaay bigger than a football) if kept alive & thriving for years, so the risk is that the ponies will glide over the mantle, triggering a "slamming shut" reaction, causing the clam shell to crush or trap the unsuspecting seahorse.
I had mine in the past with clams but the clams were on a shelf up top & the seahorses never really explored up there. Still, it is a risk factor.
