You should definitely talk to a manager; try to convince him/her that while you can keep more than one female betta together, you need the right conditions (like a heater and at least a 10g, heavy foliage and/or hidey places) and the minimum of 6 femmie bettas so you can distribute aggression as evenly as possible AND give some of the girls to hide and rest..... My sience teacher in the sixth grade had a 10g, if not smaller... but she only put in four females and day by day I'd sit there and watch the females kill each other off... It was very depressing, and a very poor example of fish keeping but I didn't know then what I do now- stores need to start dishing out the right information and while I somewhat give them props for knowing about sororities, it's hindered 10 fold by their poor conditions and obviously misleading poor excuse of a display.... If anything, bring up how much money they WOULD make if someone decided to do a sorority! All the foliage and hidey holes! A 10g+ tank instead of a dinkey glass bowl along with maybe a filter and heater! Conditioners, food, all the female bettas that would fly out of the store.... JUST from showing a proper display and giving out RIGHT information on how to do a sorority.... oh, AND they wouldn't piss anybody off 'cause obviously after the first purchase of a failed attempt, customers become discourage and start saying "Hey! Those bastards at PetSmart SAID I could do this, but all my fish died! ;__; I'm NEVER shopping there again!!!" So you'd end up losing customers in the process and making less money than you would if you did things right in the first place!!!....... >.>;;;;;; Sorry, I just.. got a little irritable is all...
