are using water conditioner? may explain the jerky movements. it is a necessity to remove chlorine and metals form the water which will burn & kill your fish
I change my 1.5 gallons 100% every three days, make sure the water temperature is the same his tanks temp, get a thermometer submersible kind is 2 dollars at Walmart, those under tank heaters? I'm not sure, I doubt they work well, I would invest in a larger tank and a real heater
