I purchased a T. Maxima about 7 days ago. I wanted to place the clam on the bottom of my tank in an open area so that it could be easily viewed. I do not have much in the way of sand on the bottom of my tank (maybe 1/2 inch) so there is really nothing to support the clam in an upright position. The clam is attached to a very small piece of rock, which basically just covers its byssal apparatus. I had heard that a clam will move enough to attach itself to something in the tank (other than this small piece of rock it is currently attached to). I was hoping it would be the glass bottom of the tank. Instead the thing fell over. Will it right itself? Should I support it? It appears to be doing fine on its side, however this is not the position I had expected it to prefer.
