Quin Hu a fish farm in Singapore actually breeds Jardini. Their are other farms in Asia too but not too many breed jars because they are not as high in demands in the markets in Asia. Also they do not have special farms just for jars unlike asian aros do. Silver are cheaper than jars and they are breed often to sell to the market. Asian aros are more expensive but high in demands in the market. It's all business, whatever can be sold fast to the public is what many of the farms focuses to breed. They don't wanna bother breeding jars regularly as they will only lose profits as not many are being sold.
