Prior to the great 'What is the smallest fish' debate, the second smallest species of fish was considered the Dwarf Goby, Trimmatom nanus. This species grows to 1 cm in length. Its printed name is longer than the adult fish.
It occurs on coral reefs of the Indo-West Pacific.
In July 2004, the Dwarf Goby was usurped as the smallest fish by the Stout Infantfish.
