The difference in color is nice. But this shows that there is no growth with this clam. Not saying it is suffering, but its not thriving. The coloration change is also due to the light its being exposed to. Clams will look different under Actinic light compared to a 10K bulb. The original shot looks like it was exposed to a 10k bulb for some time or was a new shipment.
Clam looks great though. My arguement is not that you cant keep clams under PC lights, just that they wont thrive and grow under PC lighting. Every clam is different though. You may have found one that is fine with less intense lighting. Kudos to you
