Sometime it will have its inhalant open, I think I just didn't catch it in that photo, but yeah when I have my hands covering the light it will retreat.
I check my tank about once a week and I do 10% water change weekly to make up the calcium and stuff Thanks

The clam is not gaping and looks like a healthy specimen. I would leave it and not worry about it.
A few things to moniter to keep your clam happy: Make sure your Alk and Ca are maintained. Clams can use a lot. Make sure that your Nitrate does not get too low(<2mg/l). Make sure your Phosphate stays low(<0.16mg/l) Make sure that water current does not cause the mantle to move. Make sure fish or shrimp are not bothering it. Check at night to see if there is any worms or crabs bothering it. Check at night for pyramidalid snails. They like to hide right near where the mantle hangs over the shell. Cheers, Tim

Hi Tim thanks for the reply
I will keep my Alk and Ca in checks, as for phosphate even I replace my GFO weekly I still can't get a read lower than 0.25 ( I use colors chemical checked) As for nitrate how do I keep it up? Less water change? I always get a read of 0 but there are probably some in there just my test kit isn't showing. I check everynight to see if I can catch any pest and stuff but nothing! Good thing. Here are picture taken with my GoPro hope it's better and a photo taken at night when it closed up
