As I mentioned in the article, Sakura have been showing up through regular aquarium stores, but they are pricey. Also, I've only seen juveniles for sale, not the terminal adult males. The Aquarium of the Pacific kept them at normal tropical temperatures with apparently no problem, but I prefer to hold them around 68 degrees F.
Also as I mention, the problem with bringing fish in from Japan is that you aren't paying some third-world collector for cheap fish - this is a first world country and you have to pay more. That, plus the shipping ends up being very costly. Roughly, Sakura go for $28 to $36 USD FOB Tokyo. Figure on multiplying that by 3 to get your landed cost. Add your margin, and you're talking about a fish that wholesales for probably around $150
An importer just brought some temperate Japanese animals in two weeks ago - no Sakura though.....
