The clam is under 2”, when they are small, the mantle is not large enough to provide all the nutrients from the photosynthetic process. My guess is that at 1-1/2 inches it should just be large enough to use only light but I would go ahead and provide photo.
Every two days, 1 hour before lights out. , for all four of my clams I stop all water movement for 16 minutes.
Using a syringe with a long ridged airline tube, I make a small cloud of phytoplankton right over the clam.
When you do this, watch it “pump” a few times as it takes in the photo,
In the end, what ever the clam does consume will feed your micro fauna population so everyone wins.
When acclimating a clam, it is best to start on the bottom, then move upwards.
Keep in mind your clam is a maxima and thus will love light.
Provided he is not totally closed, just leave him, all seems normal in this regard
