Torch or hammer ?

[Idech]

This coral was sold to me as a cristata hammer. It looks like a hammer to me, but when I search online, it says they are torches and shouldn’t touch other euphyllias.

The other small one was sold as a tricolor gold hammer.

I just want to make sure it’s not going to sting anything.

Thanks !

It’s a hammer. Although they can touch they will sometimes fight
