Agree depends on the species and if it's a piscivore ,omnivore, or herbivore.
This is an important component.
Even within the Central and South American cichlid community, there are herbivores like Cincelichthys , and Uaru that have evolved to get nutrients from aquatic "and" terrestrial, and algal vegetation, or some Vieja that are frugiores (fruit eaters) so tailoring food to fit the species kept is important. Just as it is when feeding piscivores like Parachromis and Petania high protein and fish meat type foods.
Also remember all cichlids have two sets of jaws. the visible ones around the lips, and the others inside the throat that grind the up edibles, and different shapes densities to the type foods they have adapted to over millennia.
Even in the small Asian cichlid community, 1 out of the 3 cichlid species is primarily vegetarian.

Also consider that the type food (its nutrients and components) may influence color traits, if properly made.
A vegetarian fed exclusively protein rich carnivore foods may not show the same coloration it would in nature where it eats flowers , fruits and other fresh botanicals.
When you compare farm raised, pellet fed fish like trout or salmon, to wild caught type in the grocery stores, this is often obvious.
