Problem with goldfish water temperature
I recently set up a goldfish aquarium and I am having a problem with the water temperature. The light that came with my aquarium is heating the water in my tank. The thermometer says 80 degrees when the light is on all day. I am terrified that when summer weather comes that it will cook the poor things. Although, we do have air conditioning. Do I just go and buy a different bulb for the hood of the tank or do I need to keep the light off part of the time? Do they need the light at night?
