My blues are really friendly and easily tamed as babies they are also the most laid back when introduced to new mice.
Most of my rumpwhites are pretty chilled out but some are not partiularly bright and then the other rumpwhites which come from a line which I have bred from black tans are far more aggressive and females are prone to dominant behaviour.
I also have some black selfs and they are the most nervous mice ive ever had, they practically leap out of their skin if I so much as look at them, im working on them though!
