Gemma. Maybe you can add some additional sources of on line Koi for Tara!
That depends what type of koi
@Tara is looking for and what quality (price) again I'm not into Showa, kohaku, Sanke etc but if I
was, I 'd trust Beni Hanna Nishikigoi, I met Mathew and his wife at the koi show, I really liked the free private class, very friendly couple. I bought a beautiful lemon dragon from them. problem is as soon as they post fish online they are sold so it's not easy buying from them until the new page goes up
I recently purchased 5 new koi ranging from 7 to 14" , they were shipped overnight, acclimated and released. They went straight to explore their new environment without a sign of having just arrived .All 5 are still doing good, schooling around in the deep of the pond.
I got 2 from Koi to the world, two from Casteway and one from E-Bay I forgot who the seller was.
You also have to consider that most places share the same suppliers like Blue Ridge, kodoma, Blackwater Creek etc so not much difference in the quality of fish, it all depends on what price one is willing to pay I guess
