It depends on how u define 'nice' goldfish. Very sorry for i am just a novice gf hobbyist. No budget for kashira ranchu. Only cheap cheap thailand/malaysia sideview ranchu.

So, for nice ranchu, IMHO, it is preferable to go to the importer/exporter/distributor outlet. So far the only major importer/exporter/distributor outlet that i have visited is Xian Leng (one outlet in shah alam) and fengshuifish (one outlet in Puchong).

There should be many distributors out there with farms and with/without outlet. Perhaps other bros with inside contacts can inform u more..

My 2 cents.
