Longfin Black Ice Clowns

[KeitoBombito]

Hello new reefer, I will be adding a pair of longfin Black Ice Clowns to my freshly cycled 110gal from my local lfs, they have said they have had them since April, they look healthy and active, and are feeding them a mix of pellet, flake and frozen food. My questions just being what's the best food to feed clowns for an all around good diet, or if I should just replicate exactly what the lfs is doing with them as they do look healthy.

Also the female does have this spot on both sides of her, thinking it's just a marking but can anyone confirm?
Thanks
