Mm, they were kind of a periwinkle color. Just a translucent "blueberry", really, so the name seems to be pretty accurate - not sure how it applies to blackberry shrimp, or if they're the same.
And yes, it is great to find these things. I was in awe. Now only if I could find something similar in a reasonably close area. I did ask if I would be able to bring the shrimp with me on the car ride, and even though they said "probably," I didn't think I'd be able to manage the task of opening the bag every hour to allow fresh air to enter while cruising 80 through traffic alone.
hmm, interesting. It's probably the same shrimp, with a slightly different coloration?
Anyway, you won't have to constantly open the bag.
The store is near my house, but 2 hours from the university. I drove a bit more than 2 hours (including stops and such) with an amano shrimp and cherry shrimp, and they did fine without me opening the bag.
And one time, I bought some ghost shrimp at 11am. I changed the bag to something more suitable at 12noon.
I then left for the university at about 4:30 or so, and didn't get there until 7pm - and they were all alive :)
but then again, ghost shrimp cost 33c here, as opposed to 6$ for the cherry.
So it may be a good idea to not be as haphazard as I was, haha.
