Chances are the clams will die under the sand and create bad conditions in your tank. I would sugest getting rid of the clams and setting up a darter only tank for breeding.

I was reading in a science journal about darters and how they are starting to drop-out because of water quality, and ecosystem problems as a result of human growth.... sad news
