We are in the process of setting up a new 46 gallon freshwater tank and are trying to decide what fish to get. My wife wants lots of color in the tank, so I was leaning towards Cichlids. But, she also said she would like lots of fish, so that may limit the Cichlids. Plus I'm not sure we want an agressive tank. Any suggestions as to what types of fish could add color to our tank? Thanks in advance.
