Yeah for me it depends on the fish. My cardinal and royal gramma will eat a bit each time I feed the tank then just sort of chill. My yellow watchman hides for a couple days then gorges on everything that passes their hole entrance. The possum wrasse eats pods all day and treats feeding time like a turbo pod explosion so they still "hunt" but they eat quite a bit during feedings that gets into the rockwork. The next tier will eat a lot but eventually seem to get full. That includes the lawnmower blenny and the anthias. The final tier is the "will eat until the food is gone" tier. The clownfish, clown goby, one spot foxface, and tomini tang are in this tier.
