On a serious note, I always preferred to give my colonies a nutritious range of food, but a little more general for cost purposes. Then I’d have a feeder bin that I’d keep about a months worth of roaches and super worms in that would get the more specialized foods.
For example, main colonies got veggie/fruit scraps+all natural whole ingredient horse chow mix
Feeder bins got some of that, but also more specific things like blended gut load cubes, fresh store bought/garden veggies, occasional supplements I wanted targeted to my animals, etc… basically just gave me more control of knowing exactly what was going into my reptiles.
There is evidence showing insects increase in nutritional value from being raised on good foods. So it definitely worth it to keep the colony healthy even if you’re not immediately feeding off. Hell, mealworms can even be pretty damn nutritious if raised properly.
