This is a room within the Dunia Air Tawar aquarium called Nusantara Aquarium, where each of the smaller tanks represent the various provinces of Indonesia (Outdated displays now that there are around 37 provinces) with a number of unique small fishes native to that province.
The two paludariums stacked there had originally supposed to represent a province, but it had been scrapped and are just a couple of ordinary paludarium displays.
