I've seen a group in an 8x2x2 tank (possibly 6x2x2) consisting of 1 adult male and 4 adult females living peacefully, but from what I understand they need about a 150 gallon to breed or the male will beat the piss out of the females.
My experience with Festae is different than yours. My female killed 4 males before accepting one. She wouldn't accept any other Festae in the tank, male or female, but ignored all other fish.
