So I will answer this question thinking that I also have resources to do what I want,

If I will not need to work I probably will own a small land and make living with fresh water fish.

I probably would build a pond beside my house where I can see my fish growing, also I can witness them having babies.

I was kinda fond of owning an aquarium since I was a child and that would probably my dream pet.

To own and have a pond with many kinds of fresh water fish
