I have used Sanyu Goldfish and Koi Food on my aqaurium service route with excellent results compared to the much higher priced alternative Hikari. Not that Hikari is a poor quality food, far from that, just at 1/3 the price the Sanyu food is just as effective in goldfish color developement, growth and especially goldfish bloat control (usually caused by poor quality foods).
