Uh oh. Danger Will Robinson.
Rule #1 in reefkeeping is that most everything a local aquarium store tells you is wrong.
Those lights (a custom sea light) fixture are power compact lights, and not enough to sustain a crocea or maxima clam, not even close. It's far from the best light for your tank. The reason they say that is because it was what they had to sell you
SPS corals will also not be ideal choice for those lights also. Montipora will be fine, etc., but if you want the killer looking SPS corals like some of the tanks on this site, you will want better lighting.
I'm guessing your LFS (local fish store) didn't tell you this, but pygmy angels will eat both clams and corals. They are usually not reef safe.
Lastly, a 10 gallon tank is a very, very tricky thing to keep balanced, even for "easy" corals, let alone the super sensitive SPS and Clams.
I'm not trying to sound negative but rather to help you avoid mistakes many have made before. I'd stop listening to your LFS immediately and start reading ASAP. Check out The New marine Aquarium by Mike Paletta or The Consciencous Marine Aquarist by RObert Fenner. They will ggive you a good start.
