Got it! Added 3 females (they are all females actually , transfered the betta and everything looks zen so far! I'm keeping an eye on them but am hopeful it will work!Fisker said:Should be fine.
I'd make sure that there's plenty of places to hide (plant cover, etc.), and I'd even consider upping the number of female guppies, if you can. It'd spread out the aggression. Totally depends on the particular betta, as well.
