Hi Alyssa,
I wondered how you know that you have a pair; have you seen any other gender differences except for the big belly?
Or am I wrong and do you mean you've bought two raphaels?
I too think that this big belly is caused by food. Do they have enough swimming space? My Orinocodoras eigenmanni will also fill themselves to the brim, but they can swim it off.
When yours is just laying down (and breathing heavily), I think you should stop feeding for some time. However, as I don't know if you have any other fish in the tank, that's easy for me to say.
Good luck with them and pls keep us informed.
