I want to have pet But i love many pet then what pet i need?

先樣金魚, 培養你嘅責任心. 樣金魚先係因為比較容易打理.

You wanna have pet BUT do you have time or patience??
you gonna have money for its medical treatment and food and toys
you gonna have patience when it's naughty as a child
you gonna have time for it because you are the only one he trust

if you think you can do all things above then I recommend you having a small dog to be with you.
