Female one is a Siamese.

Female two is a Berkshire marked Silvered Black.

Female three is an Agouti.

The male is an American Blue.

Oddly enough, I don't have many American Blues in my colony. I have one American Blue Essex buck, but I haven't really done many breeding projects with him. I guess I need to before he gets too old.

Anyway, good luck with your colony! You have some cute rats. Might want to consider getting them out of those aquariums as soon as you can though. The ventilation is very poor in aquariums.
