I believe that the various types of goldfish all have the same origin
dating back a few hundred years to Japan (or maybe China). They now
have diverse body shapes and colouring but have the different types of
goldfish had time to develop different behaviour. Dogs have different
behaviours but they have often been bred specifically for jobs that
require different behaviour whereas fish have mainly (exclusively?)
been bred for different appearances, also dogs have a higher level of
intelligence and therefore, presumably, there is much more scope for
behavioural difference.
When I speak of behavioural difference I am not so much thinking of
fundermental changes such as the way they breed, lay there eggs of
look after their young but such traits as shyness, aggression, etc.
I've got a shubunkin and a common golfish and the latter seems
considerably shyer than the former. I presume this is just a
reflection of the individual difference between these two fish rather
than because of any difference between these two types of fish which I
know have only recently differentiated. I also presume that it has
something to do with the fact that the shubukin is larger than the
goldfish and therefore dominant and that the goldfish may not be so
shy if it was with a smaller goldfish or shubunkin.
If anyone can shed light on these matter I would be very grateful.
Thanks
