Well you asked. I have a variety of fish and they get different basic diets. I like to use a variety of foods for them all.
Kensfish a mix of their flakes I came to make and did the same with his regular and mini sticks of which I have about mutiple types: veggie, brine shrimp, mysis shrimp, blood worm, soldierfly larvae, earthworm, blackworm, color enhansing and immune boosting. Some Freeze dried Daphnia.
Sera what used to be called Vipchips - Staple food (I feed to corys and loaches). I have some of their treat tab;ets you can stick to the glass.

Fresh Veggies: Zucchini aka courgette, when I was working with bristlenose, canned green beans (no salt added)
Recently added occasional frozen cooked shrimp for one tank with clown loaches and roseline barbs (Sahyadria denisonii).
I have hatched BBS for baby angels and then gave it up. I did some red wiggler worms which are easy butwill jail break all over the place if it gets dark above them. I jad it happen twice from a styro. Once with the top on and once when the light on a time went off during a power outage. So, I gave them up.
Live foods are the best for fish for which we can supply them. I chose the next best things imo.
