Fish may be smaller and less exciting animals but that doesn't mean that they are not popular. Infact fish are top three in the most owned with 11.5 millon in a U.S. household. Even if fish seem less excitng they have lots of pros. They take less maitenence, they do not take up much space, they lower stress levels, and there are lots of ways to decorating their tank. Some cons to owning a fish are that fish are not interactive at all, being able to set up their tank takes time, they are long-term pets, and they cost more than most people think.
