I give my tank 3 small feedings a day. High quality pellets at 11am and 3pm from an auto feeder. And then I do a hand feeding of frozen food at 7pm. I do this 7 days a week. I was wonder if anyone has feeding skip days. If I skip one day a week of feedings, my thought is this get the fish to search for all uneaten food in the tank and keep the tank cleaner. Thoughts/opinions?
