CMV: Fish barely qualify as pets.

Fish in a home aquarium are more like high-maintenance decorations. You feed them, clean up after them, look at them, and...well, that’s about it. As far as I know, you can’t cuddle them or train them to do tricks. 

I don’t have anything against fish or fish owners. If you like watching them swim around enough to bother with the mess and expense of having them, go for it. I just don’t understand how people can develop an emotional attachment to them. To me, bonding with a pet requires more interaction than just staring at it and scrubbing algae off the glass walls of its home.

I think it depends on the fish.  They can definitely show personality. Ive had fish that were more attention seeking or who were more stubborn.

They can be trained to do things if they are the right kind of fish. You can train them to go through hoops or swim in circles.

But if you just have a beta fish in a jar, that isn't good for you or for the fish.
