If you compare the difference between the salt water or marine fish and freshwater fish, you know that the fish for freshwater aquariums can be a bit dull and boring compared to salt water fish. However, there is one fish for freshwater fish tanks that is so beautiful and exotic it can rival any of the marine fish.

This fish is the Betta or Japanese fighting fish. You’ve probably seen them sitting In tiny round bowls at your pet store. These are the beautifully colored fish with long flowing fins that come in a range of red, purple’s and aqua’s.
