I would try dropping the dial on the tank heater 2 degrees each day and see if the thermometer on the tank drops as well.
From my experience, most heaters you will buy will actually warm the tank a few degrees higher than the setting on the dial. A 76 degree setting on my EboJaber heaters produce a 78 degree tank with a 72 degree central heating setting. Turning the dials to 78 degrees makes my tank water 80ish degrees.
The warmer water will speed up your cycling process to some degree. When I fishless cycled my most recent 55g, I kept my heater set at 84 degrees until the cycle was over.
The fish you have listed should be fine with a temp range of 74 to 80 degrees. Id shoot for somewhere in the middle; around 76 degrees or so.
