With the recent release of "Finding Dory", many people may find themselves on a trip to the local aquatic pet store to get their very own Blue Tang. Unfortunately, they might not know that these beautiful fish don't breed well in captivity, and so a high demand for them as pets is ultimately detrimental to the species. For example, when "Finding Nemo" was released, the demand for clownfish was so great that they could not be bred fast enough and were being taken from the wild to keep up with the popular demand. This is why it is imperative to always do research before obtaining any kind of pet. Luckily for beginner fish owners, there are plenty of wonderful options available that will suit your needs nicely. If you have a freshwater tank, colorful Cichlids, Mollies, Tetras, and Danios are all fantastic fish for beginners and will make for a lively tank. If you are leaning more towards a saltwater tank, Damselfish, Clownfish (now that the initial demand as gone down), Cardinal Fish, Gobies, and Blenniesare great options for your tank. However, you need to consider more than just what fish you want to have swimming around. Saltwater tanks are generally more expensive to build up than freshwater tanks.

In either case, there are things you can do to make maintaining the tank easier, such as getting live plants for your freshwater aquarium or getting a pet rock for your saltwater tank. Make sure to keep the size of your tank in mind when shopping for fish. Different species have different space requirements, as well as different compatibility requirements with members of their own species or others. It is possible you may only be able to keep one or two of a certain species in your tank to ensure safety and comfort for your fish. Make sure to talk to a professional about spacing and species compatibility before adding any new fish to your tank.
Aquariums are a wonderful addition to homes and businesses, but remember, it is always a good idea to consider if the fish you want is really the fish you should have. So the next time you feel like going out to buy your very own Dory, head to Build-A-Bear instead and make one yourself!
