Ye, you can keep them alive for multiple years in a small bowl with water change everyday, but its impossible for them. They need much bigger space than just, a bowl.This is a slippery slope thing.
Can you make a goldfish live 6, 8 or whatever years in a bowl? Sure you can if change water all the time, feed lightly, feed quality foods, etc.
Just like keeping any pet in a tiny space. You can make it work, but it doesn't mean they're being kept well.
They are free, free little fish and they should, they should be free.
I speak for their freedom, give them freedom. Give them bigger space to swim. The freedom.
