The Fish Had to Die

So I finally figured out it was the fish that were keeping him up at night. We did a night with no fish, he slept fine. We did a night with fish and disaster, he was up again playing them and playing them. So the next day I took them out. He never looked for them or cried about them not being there. He goes to sleep. Last night he slept ALL night, I never heard him at all. Hopefully, this is the end of the sleep issues for a while (crosses fingers!).
