I know some fish have it rough trying to adjust to a new tank.Is he breathing heavy?Mine turns dark when it gets scared.My lion has acted strange at times also but he usually comes out of it.If I were you I would post this in the aggresive forum.Lionfish is so gret and knowledged and I'm sure he will give you great help!!Sorry I can't be of much help!!
