The bottom one are what most people are calling "super monos". And Seiichi is calling the top one "stardust"... Not sure on the localities of them... sorry. The super monos do have all those spots in the fins in captivity. All that are in the hobby are wild caught as far as I know.
The bottom one could also come from the San Fran...The san frans tend to have more red in the fins.. but it very well could have been from the rio negro.
It would probably be around $100 for one maybe more... good luck on the hunt as those are very rare. You would have an easier time finding azuls. Unless you imported those yourself...
