Well I am not sure what happened but on the third day he just disolved. My water params are great, so I don't know what could have happened...maybe I should have put him in the sand and not on the LR. The LFS told my to put him up as high as possible for stronger lighting...so I did and that is what happened. More than the $79 down the drain, I would like to be able to keep clams and I am not sure why not.
This is frustrating.
