Freshwater or Saltwater?
-The most colorful fish are found in saltwater habitats. A saltwater aquarium is more difficult to maintain than a freshwater aquarium. Saltwater aquariums require more monitoring and can be difficult to keep clean. A freshwater system, on the other hand, is much easier to maintain. A weekly cleaning will usually suffice to keep the appearance looking good. There are many freshwater fish that are just as colorful as marine fish and will do very well in a home aquarium. When setting up an aquarium for the first time a freshwater aquarium is suggested.
