Paedocypridinae progenetica

Apparently, Paedocypris is also known from peninsular Malaysia. However, it is currently known from only one locale in Selangor. Yet, as a student who worked with Tan Heok Hui's team reveals, it might have been too late already:

I was supposed to study the behaviour of Paedocypris for my Research project in NUS.
JANUARY 2005
I visited North Selangor Peat Swamp (NSPSF) with Dr Tan in January 2005 to collect this fish. We visited all the sites that the fish had been previously collected. We could not catch a single fish. On top of that, of other peat swamp species, we caught fewer fish species than previous collections in NSPSF.
This may have been because of two reason, 1) The fish is seasonal, 2) North Selangor was in the process of being drained for agriculture, the disturbance may have caused the species to go extinct.
JULY 2005
I visited these same sites in July 2005. By this time the swamp was in worse condition. The streams were all nearly dry and overgrown with vegetation, we sampled here and again found no Paedocypris, and found even fewer fish species than we had in January.
OVERVIEW
50 species of fish have been collected from North Selangor Peat swamp forest (NSPSF), 20 of which can only survive in the acid water conditions of peat swamp forests, and a further 5 species restricted to NSPSF.
Paedocypris sp.
Betta livida
Betta hipposideros
Parosphromenus harveyi
Encheloclarias curtisoma

North Selangor is nearly completely dry, in the process of being logged and converted to agriculture. If not alreay extinct, Paedocypris and the other 4 species listed above are safely on the way to extinction....
