Clam Help

[SDFISHMAN]

My Teardrop Maxima clam isn't looking so good. My tank is a 150G
Water
1.026
PH 8.3
Nitrates 0
ALK 9
Calcium 450
Mag 1400

I have a total of 10 clams in the tank and none are showing sighs besides this one. Lighting is a 400W 20K. Any ideas?? Heres a couple pics..

Are any fish harassing it? Any inverts by it? Pyramid snails?

 

[SDFISHMAN]

No fish harassing it or inverts near it. Check for pyrimids but nothing. They would be easy to spot due to my tank being a BB tank.. Anyone??

For some reason the treardrop maxima have a poor motality. How does the byssal look? For some time, that they were being collected and the footing was be torn of the rock in the wild.

Hey Barry its been along time.. Will I have had this clam for about 4 months. The foot doesn't look to good. Today the clam is bleaching and barely open. Should I just remove it for the tank?? I don't want it to harm my other clams.. Thanks..

SDFISHMAN, It's been a while now.

I don't like to tell people to do that but they have a QT, then yes. From the way it looks, am sure it is on it's way out.
