Half my male rams face has turned black?

sorry for your loss!

how old/established is this tank? what are the water parameters?

Tank is about 15 months old, ammonia 0, nitrite 0 and nitrates around 5-10ppm. I think my water is a little harder than what rams typically prefer, but its not that different from the LFS.

It stinks, I really liked those little guys!
 
It's so difficult to find quality blue ram stock at most LFSs IMHO. Don't give up though- try getting some from a breeder. Lots of people have success with stock from Aquabid breeders, although I've never tried it myself.
