Clam wont open?

[EW_Fish]

I have had the clam over 2 months now and has always been open till about a week ago. Won't open now. Any ideas all parms are in check and have not added anything but food and my weekly water change. Its a 6'' maxi from Pacific East

What kind of lighting are you running on the tank? I've seen clams close up a couple times due to high light. Did you ever notice any change in coloration? What sort of test kits are you using? Any chance of a PH or alkalinity swing without you noticing it ie. late at night?

 

[EW_Fish]

Never saw a change in color. Alk - hanna checker the rest is red sea. Full spectrum leds.

As for the jumps in ph and alk. I have the skimmer intake to the outside and fuge light to try and keep ph stable not saying it dosnt jump.

I found one in my sump on top of my snail.... Needless to say he had a taste of bayer. Then burned.. Everything that has entered my tank gets 2 bayer treatments and 1 month qt. The only thing I did not bayer was my clam... BUT he did get qt My tank started off with dry rock dry sand so I have no idea how he would have gotten into my system. I learned my lesson after red bugs a year ago. But this weekend I will be tearing down the tank and going through to find more.

Dang, did the clam die?

 

[EW_Fish]

No but will go back in QT tonight. I'll keep you guys posted.
