I love Hiraki products and I think you were given sound advice. My problem is, is that I have been feeding my Red/White Oranda Hiraki Oranda Mini Gold for several months now and about 2 weeks ago he developed swim bladder which may have been attributed to the floating pellets. I feed him every other day now and overall he's back to normal and active but I've switched to flake and he kust sort of looks at it as it sinks to the bottom of the aquarium. I've also pre-soaked pellets and it's the same thing, it's as if he doesn't realize that that's hiw dinner sinking right past in front of his little nose!
Any ideas?
