can Tridacna's move?

[cocoa_pleco]

last night when i got my Tridacna clam, i placed it in the middle of the tank under its own 150w metal halide. It was in the same spot this morning, but i just looked in the tank and now he somehow got to the right side of the tank. he has no damage, so noone picked him up and hes upright and open. can they move themselves?

Yes, slowly, cocoa, by their 'foot'. When it finds a place where the light and currents suit it, the basil tendrils grasp whatever is underneath the substrate and solidify. You can really damage and kill a clam when it's settled.

cool. he tucked himself under a different halide between some rocks, too perfect for a fish to carry him to
