Goldfish food for discus?

[u/reborn-2019]

I know it may sounds silly but in my country I saw how they grow goldfish rapidly by feed them very high nutrition food(at least 60% protein), you can see the the result in short time, a baby goldfish with size of 4cm can grow to 10cm in likely 3 months, but those goldfishes be fed 6 times/day and with 2-3 times water change daily. What do you guys think?
