Discus fish like to have varied diet. They are picky about their pellet food but they love have treats here and there. I give them raw chicken, raw tuna, Hard boiled Egg york, Freeze dried Tubefex, Freeze dried shrimps etc and they like all those. I don't like to give them any live food coz those can give them various illnesses and digestive problems. But pellet food must be given to Discus fish to keep them healthy and as a balanced diet.
