They can be an ideal pet if you're away from home a lot or don't have the time for a more high-maintenance animal companion. Determine whether you want a freshwater or saltwater fish.
Saltwater aquariums are for more advanced fish keepers.
Talk to your pet store owner about which fish would be right for you. Don't be shy about asking for advice. Remember to ask about all the supplies you'll need, including an aquarium if you don't already have one. Choose fish that hold their fins erect, not tight against their bodies, and avoid those with split fins. Select fish that aren't hiding in corners or hovering near the bottom of the tank.
