This is a question really more about fish than cats. I've always had aquariums in my home. We had a very large one at my parents house, I've had countless beta fish live for many years, and various small aquariums. I really want to get fish. I also think my cats may enjoy watching an aquarium. But do you think that would stress out the fish? I want to have healthy happy fish and if the cats would stress them out too much then I wont get them.
