Last week I added 1 cleaner clam to the DT and 1 to the fuge. Within minutes they buried themselves in the sand and haven't surfaced since----not even their siphon tube. Is this normal? Should I try to find them?
If you are lucky you will see him blow sand up clearing the way for his tube. Kind of like a whale when he surfaces. One time an unlucky hermit was over the tube during a blow and the hermit raised 6" off the sand bed.
