Well, I am just a beginner at goldfish, but i already realise that they do need a lot of care(compare with my angelfishies). Further more when problems arise(eg: the goldfish dont look well/sick...), i will feel so worry about them and spend more time observing them and do more frequent water changes...

However I dont have these problems yet since i am still just a student. But my friends feels that i am weird to like fish so much and keep telling them about my fish... ...
