Worlds (second) smallest fish

Paedocypris

Paedocypris were discovered in the 21st century and include one of the world's smallest known fish and one of the smallest known vertebrates, Paedocypris progenetica. Two species of Paedocypris were found living in highly acidic peat wetlands on the Indonesian island of Sumatra and in the Malaysian part of Borneo.

The world's second smallest fish, Paedocypris micromegethes, found only in highly acidic black water peat swamps in Terengganu, Johor, Perak and Sarawak, is under threat of extinction following the draining of these areas for oil palm plantation.
