So my theory about Emerald Congalala is that they are older males who have gone off to live on their own. The silver hair is the untouched hair, and the green parts are mold or algae they've accumulated. The beard is evidence of their old age and the fact that they are not seen alongside congas suggests that they are less tolerant of young ones. The increased amount of flatulence also suggests that their digestive systems are starting to become weaker with age.
