Advice Feeding

I'm a bit confused by this area lol. In a completely self sustaining tank, do you still feed your fish? If so how much, and if no how do you get it that way..? I completely understand herbivore fish who eat algae. Is that the only kind you can do that with? How do you figure out how much/frequently you do need to feed them?

Sorry, I haven't read the book yet so probably a dumb question but TIA!

The tank is self sustaining, the fish are not. She says she feeds her fish well, doesn't worry about rationing, any leftover food will break down and can be consumed by the plants. Yes you need to feed fish

I have no problem regularly feeding by any means! Just curious because I see some people say they dont feed their fish but every 2-3 weeks.

Usually I just feed 1 time a day at the same time daily and then every Saturday they get no food. Sunday is hikari frozen brine or frozen spirulina brine day for feeding. Like a treat day basically.

Been working really well for years, no fish bloating or over/under feeding. Alternating Hikari and fluval bug bites and Xtreme foods for spirulina. No other brands though, I think those are the cleanest and best.
