Great...lots of real estate to work with. I just added a male betta with a group of otos, about 18 pygmys and a couple of odd corys and the tank still looks empty and he basically keeps to himself. I've had bettas that were really docile like my new one, and one that would hunt down and nip other tank mates until a feisty ram decided to teach him a lesson. So, it really depends on the personality of the betta. Until you really know what your future betta is like with other tank mates, just provide lots of ground cover for her tankmates until you feel that she can coexist peacefully in the tank.
