Although killie ethics generally say not to breed from different
collections, they do publish a cross reference. This tells which
collections are the same fish. This way they do have stock to cross if
they need it to keep a species viable.
I'm all for this idea of rainbow keepers using the similar method to
denote our rainbows. I noticed one argument that in the fish trade
we're lucky enough to get them to use the collection location alone.
They killie folks have this same problem but it has not stopped them
from developing and maintaining a standard to track their fish.
