In general, keeping saltwater fish is more expensive and more difficult than keeping freshwater fish. However, once established they do seem to be less demanding and water quality tends to stay better in tanks using live rock. Live plants perform similar (albeit to a lower degree) functions in water filtration in a freshwater aquarium. If you've been keeping freshwater fish tanks for some time now successfully the switch to a saltwater aquarium should not be all that difficult. If you have the desire, the fortitude to do the necessary research before acquiring animals and aquarium equipment and the money necessary to run a saltwater aquarium, then by all means go for it! Once you get started you'll be wondering why it took you so long to get into the saltwater side of the hobby.

Most of these fish usually will not live very long in captivity unfortunately. They usually only eat live fish and will rarely accept frozen foods. They are best suited for a species only aquarium with most aquarists who keep them only have a single fish in the tank.

Bettas are absolutely beautiful. The picture to the left speaks for itself. They do well with peaceful, friendly, and dull-colored fish. In my opinion, bettas are one of the best freshwater fish for beginners. Although bettas get along with other fish, you should stay away from mixing two bettas in a single fish tank.
