I've built a Enclosure for Ring Tailed Lemurs and have a Group consisting of 3 males and 12 Females but I just got the Notification that they are fighting because of too many Animals of a Gender. Zoopedia mentions a possible Group-Size of up to 29 males, 29 Females. Can I have only one or maybe two male Lemurs in the Enclosure or is the Fighting just a Bug?
