Smallest Fish Identified

From an article found in the BBC:

Researchers have found the smallest known fish on record in the peat swamps of the Indonesian island of Sumatra.

Individuals of the Paedocypris genus can be just 7.9mm long at maturity, scientists write in a journal published by the UK's Royal Society.

But they warn long-term prospects for the fish are poor, because of rapid destruction of Indonesian peat swamps.

The fish have to survive in extreme habitats - pools of acid water in a tropical forest swamp.

Food is scarce but the Paedocypris - smaller than other fish by a few tenths of a millimetre - can sustain their small bodies grazing on plankton near the bottom of the water. [...]
