Do you have a divider in the tank or something? Cause two bettas (male or female) generally is a bad call, the males will fight, and with the females theres not enough to establish a heirachy so the underdog gets picked on. Im curious as to how its working out!?
Personal note: I never kept my bettas with others. I didn't like forcing them to dominate or be dominated by each other. It seemed to add a lot of unecessary stress... even for my girls.
It is up to your own personal preference and opinion, but I never liked seeing my girls in horizontal stripes. That usually meant they were stressed out.... not to mention any girl will tell you that horizontal stripes are hardly flattering. :dance2:
