Can anyone give me a few of the best color enhancing foods available for fish? I am wanting to bring the reds and turquoise colors out in my fish. I know that foods high in spirulena and high in carotinoids are great, just not sure which ones have the best content of these. Currently I am feeding spriulena flakes, Formula One, and frozen Krill, along with various other things, including Betta Bites...hahaha. Thankz in advance!! Much appreciated!! OH!! If its sinkin it would be much much better!! Floating doesn't get as much notice with my cichlids, plus the over flow is so powerful its not in the tank long enough for them to really eat it anyway.
