Fish are some of the least interesting pets you can get. All they do is swim and pass away. I learned this lesson well when I got three pairs of goldfish within a couple of months, named all of them «Cosmo and Wanda,» and watched every last one of them expire right before my eyes. Although a fish is far less stimulating than a cat or a dog, they do have some unique qualities that other pets don’t. For starters, you always know where to find them. A fish can’t run away like a dog, cat, or rabbit. Whether they like it or not, they’re stuck in that fish bowl for the rest of their lives. In that way, they’re easy to observe. You can spend a lot of time sitting in front of a fish tank, given that it has enough fish, flora, and fauna to keep you entertained.
