I think you may need to upgrade to a 20g if you wish to keep them and since Males can fight to the death once mature I would consider taking one back and maybe trying to get a female. I would be surprised if they don't fight with your betta at some point too so they are probably best kept in separate tanks. Lovely fish but can be very agressive...on the plus side you have a gorgeous betta.
