I used to have a female betta and she was pretty animated and cool. Being that it's a caged animal, it's not the same as a cat or a dog, since they can't seek out affection from you, but I got a certain joy out of trying to make her happy and healthy. She'd hop out of the water and take food from my finger (that's how they hunt in the wild anyway), and flared at my roommates and people she didn't recognize. And do a little dance when I came in my room.

I had an Oscar fish that would actually let me pet it

Depending on the kind of fish, many of them actually can be quite expressive.

It's good practice for marriage.

That's a really good question actually.

I think their mostly for relaxation. 🤔

With my emotions

I actually stopped keeping fish because losing them, to me, was devastating.

I had a goldfish for 9 years...i think through the years i got attached by seeing my goldfish everyday
