I have a 55 gallon FW tank. Right now I have 2 kissing gourami, a featherfin catfish & an electric blue jack dempsey. Their temperature range is upper 70's.
I have 2 thermometers, one at each end of the tank. They both read around 82 degrees. My Marineland 300 watt heater is set to 76-77 degrees and the thermometer attached to it actually reads about 75 degrees.
Which reading do I take as fact? What's going on here?
