clams not looking well

[ac green]

I recently purchased a ponape maxima from a LFS and after about a month it died. Now a few weeks later a tear drop died on me.

I now have two others that don't look look too well. I assume the recently purchased ponape had some sort of disease and now its spreading.

Is there anything I can do to try and save these guys?

TIA!

I'd check the tank parameters to rule that out, but I also had a similar problem a few months ago that wiped out five Maximas and I still don't know what went wrong. It was devastating.

Keep us posted on the progress!
