No, this is not a shop... it's a wholesaler. It's somewhere deep in an industrial area in Subang going towards Sungei Buloh. (not the easiest to find, but sure worth your while.)

Apistogrammas are something they have occasionally. Last time I was there they had some Pandura and Agassizi. Sometimes they're very well stocked with interesting species, sometimes just the boring bread and butter fish.
