A betta in a 2 gallon tank is fine with me. Especially when they're in those tiny cups - I understand that males have to be kept separately, but those cups lead to as much tail damage and health concerns from poor water conditions than tail nipping can do.
The guy at the lfs told me not to put a betta in my community tank because of the heavy top flow from my filter, but I ignored him and did it anyway. The betta adjusted, and he has a ton of space now, and he can actually swim - something he hadn't done since he was a fry. Sure the tank might be an inch or two overcrowded, and the filter flow pushes him around a little at feeding time, but he's gotta be happier overall in anything bigger than one of those dinky urine sample cups.
What also makes me really angry are those stacking betta cups that some places sell. They're barely bigger than the urine sample cups, and they asphyxiate (sp?) the bettas. IMO a betta needs at least 1.5 gals, decent water quality (including water changes), access to air, and food (not that plant B.S.). If you got all those down, then you're a good betta keeper.

 ) what drobbins said too.
  So like 4" for any male betta instead of 2.5 
   Not that I have come to find what I think matters a whole heck of a lot in this wierdo world  
   But, I can voice my opinion here right!!!  
 
 The thing is that I thought I was doing well by them, I had read that since bettas are territorial, the smaller the space, the less stressed out they are trying to defend it and that since their fins are so long and heavy, if they have a larger territory, they will stress and exhaust themselves trying to protect it.
