There should be currently four animals at this facility. Last time I saw three animals together. Berlins founder pair came from Arnhem and Frankfurt zoo. First breeding occurred in 2010. Another one in 2011. Against thesis of solitary living in the wild, in captivity they show a high social degree. Many facilities maintain breeding pairs, in Arnhem an Prague I saw about 4 animals huddling together (presumably pairs with their offsprings). In Berlin they live together with senegal galagos and springhares.
