Gourmai and betta come from the same family so take the same sort of territories so its best not to mix them. You can easily get a nice sorority in there, but before choosing your girls make sure you watch them in the shop for ages to see their behaviour, if they are bossy or chasing the others then I'd pass on those. I spend at least 30 mins watching them in the shop.
As for tank mates I don't know, my girls are ok amongst them selves but took a big disliking to baby apple snails, however they are fine with my larger nerite snail.
