I love my divided tank! It's divided 3 ways, not in half, but I still love it. It's great to see them interact. I did have to take one out because he started tail biting, so you got to watch them for that. Good luck!
Lol thanks everyone :P Haru is extremely aggressive, so I definately wont be getting a clear divider, he has enough problems with his reflection on the tank glass let alone a whole other fish! lol It would be cute to get a girl and watch him flirt though lol
