Tan Heok Hui was born in 1971 and he had always had a strong interest in animals and plants since young. He had also started to keep fishes as a hobby since he was nine. Since entering the National University of Singapore in 1992, he started to get involved in the science of fish in a more serious manner. With the encouragements and support of his supervisor (Prof Peter Ng) and mentor (Maurice Kottelat), his family and friends, this interest was nurtured and further cultivated. Having taken part in numerous field trips in Southeast Asia during the last 16 years, he is constantly amazed at the diversity of fish inhabiting Southeast Asia. Dr. Tan obtained his doctorate degree in fish systematics from the National University of Singapore in 2003, working on the systematics of Borneo Suckers (Gastromyzon). He has, to date, published more than 50 internationally refereed scientific papers, describing more than 75 species of freshwater fishes new to Science, including the world's smallest fish species (Paedocypris progenetica) from the peat swamp forests of Indonesia. His other interests include SCUBA diving, nature and underwater photography and herpetology. He is currently a lecturer based at the National University of Singapore.
