What is my clam trying to tell me?

[awestruck]

I have had a 3" crocea for 1 week. It was opening fine when I first got it but now it only opens a crack. I just put new t5s on
my tank (it was under VERY dark lighting at the LFS). It is sitting 2/3 of the way up in my tank. My water parameters are as follows:

Temp. 81
Alk. 127.4
Cal. 440
Nitra. 0
pH 8.0
Sal. 1.024

Any thoughts? TIA

it is telling you it needs to be acclimated to new light. start out low or even put some layers of eggcrate on the lighting

Ok, thank you for your response. Poor little thing, it was like being locked in a dark basement and then walking out into the sunshine. I should have figured it was kinda shocked. How long should I leave it lower before moving it up for more light? TIA
