Odd Fish Behavior - Excited/agitated fish

[ddavis1979]

Shortly after feeding this morning, the Black Neons and Tiger Barbs were acting strangely. They were churning around one of the bonsai ornaments and darting around the tank in an excited fashion. Normally they are very calm. I was not able to catch them when they were at their peak, but this behavior was accelerated at times off the camera. The tetras were being aggressive with each other and it appeared that the barbs were trying to school with them, which was freaking them out more, but no fin nipping that I could tell. An hour later, all was back to normal. Any explanations for this?
