Trachy/brain coral

[TheLandShark]

Good day,
My tachy is eating a hermit crab live is this okay? I know elegance corals will eat hermit crabs and snails. I’ve seen it. But I’ve never seen a trachy coral this, I put in 20 dwarf blue legged hermit crabs, two days ago.

It swallowed the hole shell last night, is it going to get stuck in there and kill it?
