Description
Size: 3 cm. Distribution: Thailand. Asia: Nae Nam Tod Deng, Narathiwat Prov. The gender difference is very easy to see, for the males have broad light seams along the dorsal, the ventral and the anal fins. Moreover, during breeding time the females are clearly more filled around the belly. The male fish shows guarding behaviour for spawn and fry until the young are free swimming; breeding occurs in tubes, for example pieces of bamboo.
