I really want a pair of rams but.....

Sorry to say, but there really isn't room. If you could sell the gourami and the school of neon tetras you could add some rams. In my humble opinion the rams will be much more entertaining than the gourami and tetras and would create a more balanced tank.

Look for Bolivian Rams since Blue Rams are usually imported, in bad shape, and tend to die several hours after the stores warranty runs out. The exception would be some locally bred Blue Rams which are usually in much better shape.
