I've read some thread that most quality Ranchu came from Thailand, and there's a mention of Siam Goldfish, Thai Ranchu Centre and Absolute Fisheries, Which of them cater better quality? If allowed to ask. I'll be visiting Bangkok on Jan 8 - 11.
anyone who knows please recommend e.

All is best farm in thailand. But you may buy the fish not the farm. all they got a lot quality. The perfect ranchu is difficult to find. Or May be you go to direct with breeder like Mr. Aod Coban, Mr.Chat Ranchuart, Mr.Rat Fuji, etc. That better to find for competition. But not all time they got its.

Thank you very much and a Happy New Year... WOW, for more than 10 years as goldfish hobbyist only now I became to obsessed about them.
