First off, I am sorry to hear this. It is too bad. 
Next, are you talking about the JD that is in the 55 in your tanks listing? If so how big is it now? I think you could set up another pair with your male. But the larger and older the male is, the harder it might be. It will work better if you can get a female that will come close to match your male's size. Also I think that it would work best if you do it sooner rather than later. The longer you wait the more the male will see it as his tank. Good luck.
