i have a 4" squamosa that has been in my tank for a month now. up until today it seemed very happy with great color and mantle extension. however, this morning when the lights came on it remained closed and never opened. i come home from work and it is still closed. the derasa and the crocea, which i've had a lot longer, look good as ever. i have not ever noticed any of the tank inhabitants bothering the clam and for the occaisionaly pyramidellid snail on the turbos i have not seen evidence of infestation on the clams. what's going on here?
