my dad just brought me a garfield the cat fish bowl today (oh boy like i need another fishtank

) but of course i ran right over to petsmart to buy stuff to set it up, and ended up getting 2 female bettas, a white and red one. they get along for the most part, but they keep flaring at each other now and then.. is that alright? the white one made an intimidating face and swam up right next to the red ones face like it was going to ram into it, but then it just swam the other way Lol

do female bettas usually have the occasional quarrels? they were in the same tank at petsmart, and no one was picking on anyone else, but then again they were in a 10 gal. tank and i have no clue how big this bowl is. anyone know? heres a few pics, sry for the horrible quality, my digital cam. broke so im stuck with the webcam for now:
with the light on

and off
