Oh ok, I see in the description of this photo (
http://www.zoochat.com/14/otter-267641/) that the otters have swapped, the family (4 otters) is now in the newer enclosure next to the tigers, while the two females are now in the macaque enclosure.
Still would like to know what the plans are for the future of these guys, will they stay as two groups or be merged? I can't see anywhere for a second group to be housed on-display if not with the squirrel monkeys.
