Good find, you'll probably want to keep them separate from other rams you have, as my understanding is that if they crossbreed with browns, you'll lose most (if not all) of the blue color over a couple generations. Whereas if you keep them in a tank without other rams, they will breed true.

I've got some bright orange/tangerine colored ramshorns and so far that's been how it's worked for me.
