Bleeker wrote in 1863 : "The bulu-bulu inhabits not only the large 

 rivers of Sumatra and Borneo, but also those of Siam, where M. the 

 Count of Castelnau found it during his visit to Bangkok." This 

 statement was apparently partly incorrect as regards Thailand. The 

 fish is not known from the large rivers but seems to be peculiar to lakes 

 in Peninsular Thailand, that is, in the inner part of the Tale Sap and 

 in the Tale Noi, and in the small, short streams connected therewith. 



The recent finding of this species in Perak by Herre and Myers 

 (1937) is interesting and, taken in conjunction with other records by 

 these authors, suggests that the assumed disconnected distribution of 

 various fresh-water fishes that have heretofore been known from 

 Borneo and Sumatra on the one hand and Central Thailand on the 

 other may disappear when more intensive collecting shall have been 

 done in the Malay Peninsula. 



The full-grown fish are strikingly marked with oblique black cross 

 bands shown in Bleeker's plate in the Atlas but not referred to in the 

 description by Weber and de Beaufort. 



This is one of the common fishes of the Tale Noi, where a special 

 form of gill net is set for it and examples up to 25 or 30 cm. long are 

 taken. 



The local fishermen and those of the Tale Sap have a special name 

 for it — q)la turn.
