Are the sp. cubaris rubber ducky and the blonde two different species? If the blonde line reproduces, will they have their blonde trait? Or will they have a percentage to look like regular rubber duckys. Thx!
The blondes are a true breeding color morph of the normal duckies... I haven't heard of normal duckies popping up in blonde colonies, but I have seen lots of "half blonde" individuals show up in normal ducky colonies, which could probably be line bred into normal blondes.
I started with some normal duckies and a lot of them are blonde but you can't always tell because they are pale until they get big and can look blonde when young even if they aren't.
