Hey Matt, Karashigoi are the Yellow ones but can throw quite a few different colours like you mentioned they would be classified as chagoi i believe theres is also sorogoi (Grey), kigoi (White), ochiba (Patterned), an some others that come from this spawn. So its difficult to know what to keep so I've just kept a few thousand an let grow see what happens.
