Which food is best for flowerhorn? XO humpy head, GRAND SUMO or BRINE SHRIMPS?

i'm not an expert on fhs.. But i would say brine shrimp is a good supplement.. & i think the hump or kok contains fat, & the fat rich brine shrimp, beef liver helps to increase the size of the kok to an extent.. & mostly the size of the hump is genetic & these fat rich food just helps a lil..i don think humpy head & grand sumo helps.. Thats what i've seen in some forums.. Better wait for an expert's comment before jumpin into any conclusions..:) good luck..
