Tropical Fish Aquarium Temperature. Tank I am going on vacation and my automatic fish feeder Fish Mate has been soaking my fish food I got an air pump as the company that makes them recommended and does not work at all any advice. The safest rule for heater size is 5 watts per gallon so 100w is good for your size aquairum.
Although tropical fish can survive in water ranging from 72 degrees F to 82 degrees F it is best to hover around the 77 degree mark. But some species like goldfish and danios will survive in temperatures as low as 62F while another handful of tropical species like discus and cichlids can live in temperatures as high as 82F or even 84F. Some kind of research must be done on the fish to know their ideal temperature which suits them warmer or colder.
The good news is that you can purchase a stick-on thermometer that is able to be mounted on the side of the tank.

Freshwater tropical aquariums should be kept at approximately 77 degrees F for optimal fish health. Most aquarium heaters are preset to 25 Celsius 78 Fahrenheit and thats the temperature that an average tropical aquarium should be. Tropical fish are those that require heated water generally in the range of 75-80F 24-27C.
