Clownfish Question
 

About a year ago my clownfish got into quite a fight and I ended up seperating them. One of them looked almost dead when I took him out, but is now thriving in my smaller tank. However I'm taking down my larger tank with my other clownfish and I was wondering if there was any way to pair them up again. Before the fight they were happily together for about 2 years. If you have any ideas I would love to hear them.

what species are they?

How large are they now?
