If you're fascinated by aquariums like we are, you might have WONDERed whether the fish in aquariums swim in freshwater or saltwater. As it turns out, aquariums can be filled with either freshwater or saltwater. It just depends upon what kind of fish you want to raise.
There are thousands upon thousands of different types of fish all over the world. Some live in freshwater, such as rivers and lakes, while others live in saltwater oceans. If you want to raise fish in an aquarium, you need to create an environment for them that's similar to their native environment.
You can get a variety of different kinds of fish at a local pet store or exotic fish store. Freshwater fish frequently come from farms where they are raised to be sold in pet stores. Some popular types of freshwater fish include Bettas, Angelfish, Goldfish and Rainbow Fish.
Saltwater fish tend to be wild fish from the ocean imported from all over the world. Saltwater fish require a special environment that includes consistent temperature and water conditions. Oceans, because of their size, tend to stay the same most of the time and change very slowly, if at all.
To mimic ocean conditions in an aquarium, it's often necessary to use a larger tank that can hold more water. You also have to keep a close eye on the tank's water conditions to make sure water temperature and chemical levels remain constant.
Some popular saltwater fish varieties include Lionfish, Clownfish, Seahorses, Eels, Groupers and Angels. Angels, for example, are very beautiful, but they can be very difficult to raise because they are sensitive to even the smallest changes in water quality.
With the proper care, though, Angels can live up to 10 years. Just be careful when choosing neighbors for Angels. They get along well with other species, but they don't like other Angels!
Like all animals, fish require regular feeding. You will also need to monitor the temperature and quality of the water to make sure you're providing a quality home for your fish. And like your room, aquariums need to be cleaned on a regular basis to make sure you maintain a safe environment where your fish can flourish!
