No worries, just adding my 2 cents. I have kept fish for many years, have also owned several FH, and spent a decade working in the fish food industry.
Tropical looks like Tetra/Sera etc to me, a common theme in EU made food is to jumble ingredients with non specific terms & names, something I personally don't like. Several years ago there was a company in Britain that had almost identical ingredient listings. New Era, but they eventually went under.
From Tropical's website:

What are cereals, corn flakes? Same with vegetable protein extracts, and derivatives of vegetable origin? Pretty general listings, and consumers have no idea what or how much they are using in each formula.
And how do we know what their definition of "low starch" is? FH do not require high protein, and are not carnivores, so they already missed the mark there.
I'm glad that your fish are doing well on it, but this is not what I would consider getting back to the basics. Back to the basics IMO would be to feed your FH a quality food designed for omnivorous cichlids.
