Please help me save my clam!

[Salty Brother]

For some reason my clam is on the decline, I dont know why too, all params are fine, all other fish and corals are fine. So if you could just help me try to recover it that would be great.
Here is a pic from a month ago when I got it...

and here is a pic of it today...

I dont know what happened to it. All help is greatly appreciated.
Thanks,
Patrick
