I will be trying the Azayaka Ranchu Pellet with my ranchu and I will report on the results. The bags arrived quickly direct from Japan and were very well packaged with bubble wrap. I will begin feeding the juvenile formula (blue bag)to some of my cbr & junior tosai straight away. A lot of my adult ranchu are currently asleep in their winter hibernation, so I will test the balance (green) and color enhancing (purple) when the time is right. Azayaka is available at my friend Alexander's blog here:http://highranchu.blogspot.com/p/azayaka-ranchu-sinking-pellets-azayaka.html
Update 3-20-15 My initial impression is that the Azayaka is a very high quality food. I will continue to use it this summer.
