I know New Alameda Aquatics has a deep blue tort, I'm unure if they have any for sale as it was part of their neat show colony that apparently got a few frags knocked off during cleaning, to which I picked one up. It's still blue, but does have some green closer to the body (i'd guess from lack of light getting there) but still looks nice, unfortunately like other torts it is a slow grower and not even ready to frag off pieces.
