The dwarf pygmy goby or Philippine goby (Pandaka pygmaea) is a tropical freshwater fish of family Gobiidae. It is one of the smallest fish in the world by mass, and is also one of the shortest freshwater fish. Mature males can reach up to 1.1 centimetres (0.43 in) SL, while the females can grow up to 1.5 centimetres (0.59 in) SL. Average weight is from 4 to 5 milligrams (0.00014 to 0.00018 oz). It is known as bia and tabios in the Philippines.
P. pygmaea is primarily a Philippine species that was endemic in the rivers of Malabon, Metro Manila. It used to frequent shady river banks in Rizal Province of Luzon, Philippines. It has also been collected in the sea at Culion Island, near Palawan, Philippines. It also thrives in brackish waters and mangrove areas of Indonesia and Singapore (1992). It had been imported into Germany in 1958.
Dwarf pygmy gobies survive in demersal, freshwater, brackish and marine water environments at a pH ranging from 7.0 – 8.4, a dH range of 30, and at tropical temperatures measuring from 24 to 30 °C (75 to 86 °F).
A colorless and nearly transparent species, the dwarf pygmy goby has a moderately elongated and robust body. Males are slender with nearly straight dorsal and ventral profiles, while the females appear stouter with the dorsal profile slightly curved, the belly protuberant, and the ventral outline strongly arched.
