KUALA TERENGGANU: 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.
Ichthyologists are concerned that the fish sensitive to changes in its water parameters, may not survive the destruction of its habitat, which is also home for some aquatic species unique to peat swamp already under the International Union for Conservation of Nature (IUCN) red list of endangered species.
Measuring just 11 millimetres, Paedocypris micromegethes, is also being collected for the aquarium trade and despite its status as a rare and endangered species, it is sold for as cheap as RM3.30 per fish.
Ichthyologist Dr Zahar Azuar Zakaria who found the latest specimen of Paedocypris micromegethes in a peat swamp area in Sibu recently voiced his concern that the development of oil palm plantations in the area may soon wipe out the species.
“I have seen another Paedocypris species, the P. carbunculus traded as ruby rasbora in Singapore. I believe two other species like the P. micromegentes (Malaysia) and P. progenitica (Indonesia) are also being sold in the aquarium trade.
