oooook, lets get one thing straight here about the chingmix, it is not a miracle food, kok, color, pearling, it is all in the genes of your fish, if your fish does not have the gene for a large kok, chingmix isnt going to give him one, same goes with color, if your fish has bad color in its gene pool, then chingmix isnt goin to turn him from gray to red.
HeadBooster and Maxima have the exact same ingredients, just different amounts of each ingredient to enhance more of different things. i say use Headbooster first cause it takes longer to boost kok then color, and having the same ingredients in them, they will both boost color and kok, just ones does a better job with each.
i would only recommend chingmix if you plan to stick with fowerhorns and you eventually want a high grade (masterpiece) flowerhorn. if this flowerhorn will be the only one you ever get, and you dont have intensions to eventually buying a very nice high grade flowerhorn, then i would stick to feeding NLS, Omega, Hikari Bio-Gold, Bloodworms.
one thing that will make color just as nice as chingmix will is just market shrimp from the store, it will increase the red color in your flowerhorn, quite often, more then chingmix.
as long as you take care of your fishes water and give it a good diet, the kok should come out to.
if you do plan to keep flowerhorns for a long tie and plan to buy a high grade eventually, pm me and ill give you some ideas on good foods for them you can special order through some of my buddies on one of the flowerhorn sites (dont know if im aloud to post links to other forums here)
and again. if you have any questionsjust shoot
