I think I will stay out of the merits of the "all natural" diet debate. :grin2: That can go on a tangent real quickly. Hehehehehe.
I honestly just feed the animals for my convenience and amusements more than for their benefit. Any benefit they derive from my antics is purely incidental. Some days I feed 3x/day. Other days, maybe 2x/week. >

I culture live Daphnia because I really enjoy seeing them get hunted.
D*mn Nature U Scary!

Disclaimer: I keep
Boraras spp.,
Sundadanio spp.,
Corydoras pygmaeus,
Danionella translucinda, snails and all types of hardy/sensitive dwarf shrimps.
Their main diet consists of flakes that I have no idea where I got them from (I don't recall buying any.) and decapsulated brine shrimp eggs (DBSE) from brineshrimpdirect. No fuss. No mess. I normally just throw everything in and let the water current naturally sinks them. This presents a challenge as my fish never let anything reach the bottom. Feeding the bottom dwellers require a little bit more effort. For them, I add some DBSE to a cup with some water. Swirl a few times to make sure the eggs have sunk. Add the resultant mixture to the tank with the filters turned
off. In five minutes, all the eggs would have sunk to the bottom. Then the filters get turned back on. The DBSE will have adhered to the sticky biofilm that develops on all the surfaces (including plants). The filters get turned back on. The DBSE do not get swept away because the biofilm is really sticky! The bottom dwellers then get to work on vacuuming up everything. This is really just for the
C. pygmaeus's benefit. If I don't keep them then I wouldn't bother going this extra step since the shrimps are content hanging upside down and grabbing food bits from the surface. Baby shrimps and baby fish have no problem chowing down on the DBSE: small enough to feed the fry and large enough for the adults to clean up--unlike shrimp-specific powdered baby food which fouls the water really really quickly. DBSE are very high in protein (>50%) so those things will grow very fast. I keep everybody in a planted tank so I am sure they can find the other plant-based protein content from the aufwuch growing everywhere.
