One of the simplest but most important things in maintaining a fresh water aquarium is to keep it at the proper temperature. So what should the water temperature be in a fresh water aquarium? That depends on what type of fish you are keeping.  For typical fresh water fish, the temperature should be between 70 and 78 degrees.  There are some other fish that require higher or lower temperatures. For Beta’s, the temperature should be a little higher, between 75 and 80 degrees. Goldfish should live in water that’s a bit colder, around 68 degrees. Blind cave fish can take temperatures between 63 and 75 degrees.

The key is to keep the temperature consistent. Temperature fluctuations can kill fish or cause diseases. Set the heater at the proper temperature and wait until the water reaches that temperature before adding fish.

As for the lighting, keep the aquarium light on between 10 and 12 hours per day.
