I just got a cleaner clam from here yesterday, and i seem to be having an issue. It has not burried into the sand, or even moved since i placed it in the tank. Do you think it's dead?
I got 2 from here a few weeks ago. Neither one showed any signs of life for about a week, but I couldn't open them with my hands either so I left them in the tank. Finally they started opening just a little bit. Within the last few days they've been opening a lot, but never buried themselves. This morning one was dead, but I'm not sure why. They really seemed to finally be doing well.
I got cleaner clams from SWF about a month ago. When I put them in the tank, the buried themselves right away. I like to dig around and find them when I do my weekly water change, so that I can pull them out and make sure they are alive. I did not burp mine either - this site instructed drip aclimation, which I did. They are doing great - no nitrates!
