Wasn't there something about Black crested macaques, Babirusas and Anoas ? Or was it Wild buffaloes ?
As far as I heard, they wanted to replace the water buffalos with bantengs.
Next to this, they are currently remodelling an exhibit which is indeed going to display black crested macaques, babirusas and asian small-clawed otters.
So far, I haven't heard anything about anoas. But who knows...
