I visited a couple of times in the summer and Autumn of 2019, roughly around the time when I joined this site.... and I saw both Malayan tapir, bearded pigs and muntjac using those enclosures.
I can say with 100% certainty that I didn't see any red river hogs or babirusa in those enclosures during those visits.
Without derailing too much further, I visited in early December 2019 and the former Bearded Pig enclosure was undergoing redevelopment ready for the Red River Hogs, which had arrived by March 2020 when I saw them in my last visit before Covid lockdown. The Bearded Pigs were PTS in November 2019 I believe. The Babirusa arrived in summer 2020, post March-lockdown.
