I'm looking forward to getting a blue ram myself. But not for awhile. I was thinking of getting a pair, but after reading people's experiences, I guess I will refrain as I don't want the extra aggression toward my other fish (planning on cardinals and tetras) during spawning season.
As far as getting blue rams, you can get them from liveaquaria, although it's not worth it if you're just getting one or two. The shipping cost is overnight for $35, so I'd order from them if you're getting a lot of fish.
