Since this is a Asian themed tank, you could add some gobies, like for example the Taiwanese Dragon Micro Goby (Schismatogobius ampluvinculus) they are very cool little guys from Japan, and Taiwan You could also add Malayan Yellow Pygmy Catfish (Hyalobagrus flavus) they are very small catfish that remind me of Pygmy Cories Both of these fish are somewhat rare but extremely worth keeping
