Before we can actually see if we are dealing with species crossing we need to determine the true identity of the species involved. The so called 'aeneus' group is a very confusing one, and many may be proven to be just regional colour form and I think it will take science a long time to sort them out
The C. sp. CW23 (Orange laser), also known as C. sp 'Orange stripe' it is very close to C. aeneus in colour and shape, in fact there are a number of C. aeneus looking species which possess anything from a gold shoulder flash to a full gold band along the upper dorsal scutes, the most prominent of these being C. sp. schultzei. It very likely that many of these C. aeneus types will interbreed if kept together.
Because of the similarity in patterns of many of the regional forms, there is every likelihood that many if not all of the Asian farmed C. aeneus are actually hybrids. This is also evident in C. paleatus and its similar look-a-like species.
