Patrick, whoa on moving the clams!!! Who told you this?? Unless the clams are sitting on soft sand with nothing underneath, they're almost for sure attached to something. Removing them and breaking this attachment WILL kill them. They also just don't like being played with.
Just add the DT's to your tank and they'll do fine.
I've had three clams..I moved one..it's dead. I left the other two alone, they're alive. Pretty simple. :D
