I recently noticed my fish were gasping at the top of the water, I tested and everything is fine then somebody suggested that the temp was too high. Until today id just gone on my heaters thermosat which was set to around 74 but today I invested in an actual thermometer and to my surprise found that my tank is in the mid to high 80s! So obviously I've gotta start cooling the tank down, just wondering how quickly I can do it without shocking the fish? I'm just planning on turning the heater down a degree at a time.
