Turn off all power heads / return pump ! Lol I am very active with my tank meaning I like to feed everyone individually even the corals. Of course 90% of the time I just feed with all pumps on , I only do the feed individually like once a week , it’s fun to feed zoas / corals and I even had a mantis shrimp that would swim with the fish begging , it can also increase your fish to associate you with food good or bad
