A great looking fish to be sure.
To answer the OP's question, I tend to feed both Hikari and NLS, but more NLS lately because of the ingredient list of Hikari (fish meal, corn, yeast, gluten as the first listings kinda bums me out).
Having said that, I've never really had issues with Hikari and my fish have actually seemed to like it more. They often spit out NLS at first.
edit: I just noticed this thread was from 2017...oh well!
