@Fargusno It's not a paludarium really, just a really big aquarium. The main inhabitants are a pair of pirarucu as well as other fishes like pacus, alligator gars, an wallagonia catfish, an silver arowana, and barbonymus gonionotus, redtail catfish, several tilapias, a school of osteochilus vittatus, and an pig-nosed turtle.
