Coments (Zhou Hang per Email)

A common widely distributed species which can be easyly found in nearly every water.
In the southern Zhejiang-Profince at the Wenling city is a region where the distribution line between Macropodus opercularis and Macropodus ocellatus is clearly separating both species:
If one travels slightly north, only M.ocellatus will be collectable,
do you travel slightly south, only M.opercularis will be found in the collecting nets!

In other regions this distribution line is not of this exact way. There both have overlaping distributions.
