How should I help with stress

Apollo got moved into a new enclosure only after a month of having him. The enclosure i first built wasn’t the best and I wasn’t satisfied but he loved it. I changed him into a better one but for the 2 days he’s been eating a little less but is still eating . I figured it was stress but should I be concerned?
