Could be just shock of new tank, how big are the fish? Did you take water from the 10gallon to put in the 2.5gallon or you filled the 2.5gallon with all new fresh water? Check your water temps and make sure you treated for chlorine/chloramines etc.....you may consider bigger tank but use a tank separator to keep them from being able to fight each other....
