What temperature should the aquarium be kept at?

Most small tropical fish will live within a temperature range of 70-78⁰F (21-25⁰C). Some fish will need more specific temperatures, again, your research will tell you this.

Monitor the temperature of the aquarium with at least one thermometer, not by the reading on the heater. Place the thermometer as far away from the heater as possible.

If you have two thermometers place these at opposite sides of the aquarium. This will give you a more accurate idea of the temperature throughout the aquarium.
