|Following the cessation of the C-number coding by the German DATZ magazine, and with the ever increasing number of corydoradinae species that were being discovered, I thought it was necessary to continue with a similar coding system and introduced the CW?codes in 2006. A similar procedure and information is required before a species is allocated a code number. Firstly quality image/s are required and a verified catch location, the catch location may not always be available because in the cases of rare and or valuable fish the original collector may not want to divulge this information to avoid competitors invading his catching areas. In these instances the river systems are often good enough to be able to compare and separate like species.|
|In certain cases a CW?code has been given to identify distinct colour form of particular species, this is becoming more prevalent with species that have a wide distribution.|
|CW001 - CW020||CW021 - CW040||CW041 - CW060||CW061 - CW080|
|CW081 - CW100||CW101 - CW120||CW121 - CW140||CW141 - CW160|
