Unfortunately not. What I did when I ordered was a asked for specific details and sent a picture of what I wanted and they were nice enough to try to catch the closest one they could.
I'm not naive enough to think somebody went through all their stock for hours looking for a singular fish, but I do believe they made an effort.
I also need to amend my story here as the details of my order are coming back to me. I originally ordered the pair pictured from LA. One is indeed a Picasso, the other a snowflake. My snowflake went carpet surfing one evening. I ordered both a Picasso and a Black Ice from CR. I asked specifically for helmets on both. I asked specifically for the picasso's white to be continuous with no breaks at the dorsals, and I asked specifically for the BI to have a clear break between the front and the back.
I was originally going to pair the BI and the Picasso I ordered from them, but when I got them I had a change of heart and dropped the two picassos in together and they've been like peas and carrots since.
