As far as getting the best of its color. Provide adequate aquarium size, temperature 78 to 82 degrees. Strong filtration at least twice the gallon of the tank. weekly water changes. Avoid super bright lighting. I use natural light from the window. but make sure it does not shine directly on the tank. Feed high quality pellets such as New Life Spectrum, Hikari, Omega one. Please avoid Flowerhorn branded pellets as they are usually overpriced scams that have too much protein and often have hormones even if it does not have it labeled. If you you are going to use a flowerhorn red color enhancer. Don't use it more than twice a week. It can burn the fins and body of the fish. The kok and color of the flowerhorn is mainly from the genes so just provide the care above and remember to treat it like a normal cichlid. That way it will live a long life. ALSO AVOID OVERFEEDING. Honestly if you do need one pellet. New Life Spectrum is the best on the market. Flowerhorn in my opinion live the healthiest lives on just high quality pellets. If you are going to feed anything other don't feed it more than once a week. Flowerhorn achieve the best color with variety. so having 3-5 different quality pellets can make a huge difference.
