Unless your tank is stocked and fed heavily I wouldn't worry. You always have water changes as your safety net (I find many corals, especially lps and soft, prefer a "dirty" tank)
Fish get very accustomed to programmed feedings so I do agree that it is probably looking for a feeding because that's what it was used to. As melosu stated, I would feed either every other day or every day, but in small portions. If you choose a daily feeding schedule you can halve your portion for that day and feed twice
