Paul,
Unlikely, even if anyone was using it solely, that enough time has gone to offer any worthwhile observations. As with all things koi.. slowly, slowly, catchy monkey!
For what it's worth, I used the previous food for sometime and found it comparable to other top end Japanese pellet foods, as with them all, from Japan, the freight makes them expensive but, in my experience, still well worth it, across the board, compared to UK produced foods.

Marco,
I see you're in France. How big is koi keeping in France? I have to say I didn't know the hobby was in France at all. What dealers do you or don't you have, where do you buy your koi from?
