Are they one and the same? is dinvinci and Picasso one and the same? or are they different kinds?
I saw liveaquaria.com has Picasso on sale now. Check out this link:

Picassos are Percula. Davincis are Ocellaris.
California Reef has some Davincis and maybe some Picassos. Aquatic Collection has a few Picassos.
Bought black and white ocellaris online (liveaquaria.com), and they did not even make it through quarantine. The problem with buying the designer clownfish online is that they ship way too small ones. The ones I got were really really small like 0.25 to 0.5 inch. They would eat one day and won't eat for couple of days and kind of in the borderline health. Liveaquaria did refund me my money back though. I recently saw some beautiful designer clowns such as frostbite, Wyoming white (may be) in Neptune Aquatics that were decent size, and looked amazingly beautiful and you might want to try Neptune Aquatics and they may have Davinci/Picasso (I'm not a pro in identifying the designer varieties). I might buy soon from Neptune aquatics. I would like to buy black and white ocellaris for sure. currently I have a regular and a misbar and they look awesome. Those are my wife's favorite in the tank while my favorite is the PBT.
Darwins are not considered designer clowns, since they are a naturally occurring variant. There are a few people in the Bay Area breeding them, and all of the LFS should have them or can order them, so there shouldn't be a need to order them via an online site. I'm surprised that LA would send out such small clowns. I only sell clowns that are at least 1" in length, unless people specifically ask for small clowns from the same clutch.
