I also think that many aquarists feed too much. In the main this tends to be beginners or those of limited experience. Even the more experienced are sometimes guilty.

I feed daily but watch carefully to see if interest wanes, at the first sign of this I stop. I also monitor the body shape of the fish, ensuring that they are not fat or becoming thin.

I don’t think that fish will be sustained by aquarium sourced food alone. I do think that in an aged reef aquarium there should be food to be found that could reduce the amount needed from the aquarist.
