Corucia form tightly-knit extended-family groups. They also have an established territory in the wild, marking and recognizing it (and other members of their group) by scent. I am not sure what the composition of those groups is in the wild, but in captivity you can't generally have more than one adult male in a group. I try to keep mine in 1.2 trios (plus their babies). The babies don't reach sexual maturity until they are three or four years old, so they can stay with the parents for a couple of years. (I would not recommend separating them from the parents before they are at least 4 months old -- they need the emotional security of adults around, and they also need to acquire the gut bacteria needed to digest their food).
The males will AGGRESSIVELY defend their pregnant females, and *all* members of an established group will AGGRESSIVELY defend any baby in the group (at least for the first few months of the baby's life). We are talking "launch-themselves-across-the-enclosure-and-try-to-kill-you" aggressive. Even previously docile animals will show this behavior. (Really makes cleaning their water bowls an adventure!)
It can be extremely difficult to add any new adult to an established group, but (supposedly) babies are accepted readily. I pulled all the one-year-olds from their groups this fall, so the groups wouldn't get too crowded with the expected crop of babies this year (they seem to like to give birth around November-January in this part of the world), and set up two new groups (one 1.2 trio and one 1.1 pair) with the yearlings, and aside from a little indignant huffing, there was no bloodshed. But I have tried to pair up two-year-olds in the past, and had a lot of aggressive behavior. Introducing an unfamiliar adult male and female can sometimes be very hazardous, too. (I have a few tricks I use, but nothing is foolproof).
In that last picture (of the one-year-olds) those two were in the process of changing from their baby pattern to their adult pattern. So they won't stay that way. No way to tell exactly what they will look like as adults. (That's part of the fun!)
(See what happens when you get me started talking about Corucia?)
