Platys With Betta Sorority?

[guppy2002]

I have had my betta sorority for about 3 weeks now. The girls get along GREAT. It's 3 beautiful crowntails. They don't even chase each other. I was wondering if I could add some plates to their tank. Would that work?
Thanks

Personally I would leave it just as a soriety, platies tend to do better in harder water than what bettas will. Also platies can get nippy and if you end up with a pregnant female they will keep dropping more babies than you eventually know what to do with.

Is that 3 male bettas?

What size is the tank?  You really need at least 2 more female bettas for your sorority to have any chance of really working out long term.  I wouldn't add platys unless the tank is at least 20 gallons.
