ABSTRACT. — The local distribution and status for gouramies of the genus Trichopodus in Singapore are reviewed. Of the three species recorded, i.e., Trichopodus trichopterus, Trichopodus pectoralis, and Trichopodus microlepis, only Trichopodus trichopterus is native. It is also the most common and widespread. Trichopodus pectoralis is thriving but uncommon, and Trichopodus microlepis does not appear to have established populations.
