I agree with the above post.
With PC lights, your options are a deresa or squamosa.
T. gigas would be another choice, however, this would be worse to add to your aquarium due to its size.

If I do have good water conditions in the 5 gallon, (I run a penguin mini, about 6lbs LR and some macros sitting in the tank) and I have my dads tank which is established w/ metal halides, could I keep the clam in the 5 til it outgrew the 5 and put it in my dads reef?
I would not do that. Such small aquariums will not have stable water conditions (temperature, pH, and Salinity may change quite quickly) and will not suit any tridacnid clam.
