Female Bettas.

They are super hardy, can live in some pretty bad conditions, colorful, and you can get like 6 of them together.

No, you can't, not unless you have a larger tank. Yes, they are less agressive then males, but that is from perspective of the males being mean as can be. The females, if memory serves, can still be quite vicious.
 
It's called a betta sorority, and there are some who can pull it off, even in 10 gallon tanks. I tried it last year, 29g with 10 female bettas, planted, really pretty tank. It was successful for 6 months, until the females matured. After a year I tore it down, got tired of moving females to different tanks to regrow their tattered fins. It's def not a tank situation for the rookie.
 
I stand corrected. Never in my experiacnce have I met a friendly betta, male or female, so I wouldn't have known.

Depends on perspective. If you are used to dealing with community fish then yes, Bettas are mean aggressive little creatures. If you are used to dealing with barbs, cichlids, or puffers then they are pretty calm fish. Bettas are really for the most part only mean towards their own kind or calmer fish that don't fight back. Put them in a tank with something that stands up for itself and the Betta quickly becomes a normal calm fish (or dead). A Betta sorority isn't impossible, but it requires some balancing. Bettas need somewhere to retreat too when the pecking order starts to get established. In the typical tank there is no where a male can hide from another male (although this isn't always true) but with plants and decorations a 10g can have enough hiding places for a small group of females.

I'm not so sure you need to stand corrected. I'm not entirely sure a betta community can be successfully done, as IMO, success is def longer than the 8 months mine was set up. Once my female bettas matured, they started beating the $%^& out of each other, and I had enough hiding places (thinking more places than bettas in the tank). I've never read of a betta soriety being set up for more than a year, I could be wrong and they can be out there, I just have never read of one.
 
a betta community can be done in a bigger tank but never would recomand a 10 gallon, for 6 i would do atleast a 20T/or long, maybe even a 29. but deff not a 10. tried helping her, will help more if she wants but not forcing myself to help someone that isnt willing to accept, already told her to wait but she didnt listen and got the fish without telling me ( even though she doesnt need permission from me but still )
 
The trick to a betta sorority is low numbers. It isn't 6+. Maybe 3 in a 10 gallon but a tank that size is pushing it anyways. I'd given at leasdt 5g per betta personally, 10g preferably, if I attempted it again.

It all depends on temperament too. Which is tricky since the more you add the more likely you get a mean one that'll make the whole system fail.
I won't say I disagree with what londonloco said though. I haven't looked into it enough to say for sure, but it does often end in some form of failure.
