I remember both groups in there.The smaller exhibit was previously used to manage Haoko and Shabani for a short period of time; as well as Kibale and Kimya, who were briefly paired up in the early 2010’s.
Kimya didn't respond well to Kibale and she was swapped for Mbeli and Johari. I honestly don't know what Taronga planned for their gorillas since it was pretty much just going to be Kibali plus Kimya and Frala once her sons left. That move was delayed due to the earthquakes. Her sons also spent time in that exhibit until they were sent to NZ in 2015.
