I have a lovely gold gourami who I think is a female, she is pretty stunning but I feel a friend would be better for her, would she mix okay and become friends with another different type of gourami or should I buy another goldie? I would try very hard to get another female but sometimes in my local shop its hard to see when they have just had a delivery though they do spend ages trying to get the right sex for you!! She lives with 3 mollies by the way as I have just started stocking the tank! 
ETA its a 200L btw.
