How long should sheets of Nori secured with feeding clips be left available to simulate continuous grazing activity?

Answer

For several hours

The natural behavior of the Yellow Tang involves constant grazing throughout the day, picking off small bits of algae. To replicate this crucial time element of their natural diet cycle, hobbyists should ensure the provided food, such as Nori secured by a clip, remains available for several hours, far exceeding the brief time required to gulp down a small serving. If the feeding clip is only left in for a short duration, like 15 minutes, the fish misses out on the required continuous activity associated with eating, even if the scheduled feeding volume is met. Uneaten portions must be removed after several hours to prevent water fouling.
