I have kept and bred fancy goldfish for years and there is no substitute for hikari floating pellets. The food is clean and high quality. Importantly, you can soak it before feeding, to avoid the bloat that is caused by feeding most dry food to susceptible goldfish and causes them to be unable to regulate their position in the water - floating to the surface and fighting their way back down, due to eating dry food. Hikari, soaked, keeps its shape, does not flake or dissolve, and continues to float. The fish can take a piece of soaked food as easily as a dry one -except the soaked one will be twice the size. There are some fish with air bladder problems that will not be helped by soaked food, if it's not caused by digestion. But many that struggle with water position issues after eating will. The food has a slightly fishy smell, but it goes away when eaten.
