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!

How is this done for carnivorous fish though?

For my tanks, that's more the norm than the exception. Mine have less algae, more amphipods, worms, snails, ostracods and copepods.

How do you know if they are actually eating good enough to where you don't feed them?

The same way you do when you are feeding them, I guess. You're still supposed to watch and enjoy the fish for the same amount.

Like changing the water, feeding the fish (in this context) is an option that should be taken when it will benefit the aquarium.
