The Medaka arrived in great shape. They were active and eager to eat just hours after being added to the patio pond. It's been about 2 weeks now, and they are slowly growing and starting to color up. No unexpected health problems or failure to thrive. I've ordered this same strain (Youkihi) from Aqua Huna before and after they've been outdoors for a couple months, their color looks amazing, very deep orange.
I've done a few orders with Aqua Huna over the years and have always been happy with the health and quality of the fish. I decided to do the fish a favor and use overnight shipping this time, but I've done priority mail in the past, and that was fine as well.
Ordered 12 pygmy's and almost 2 weeks later all still there. Well packed, reasonable overnight shipping. Thanks Aqua Huna!
