It was recommended to me to have 2-3 females for every male, and a group of at least 6 guppies. I used to have just 6 males but they kept fighting so now i have 2 males and 4 females and they seem to be peaceful.
Someone please correct me if I'm wrong.
This is what I learnt doing a pre veterinary nurse course.
Guppies are generally a peaceful fish that does well in both smaller and larger groups but they prefer to be at least 2. Like all fish, you get the odd bully but that's down to the individual fish and most pet stores will allow you to return aggressive fish. Also i believe it is recommended to have all of one gender in smaller tanks to avoid becoming over run with fry, and males are preferred because females can carry the sperm for a long time.
