What temperature should freshwater aquariums be?

Answer 1

The required temperature of the water depends on the species of fish you keep and can vary greatly. Most/many livebearers like guppies, plattys, swordtails etc will be happy at around 65F to 72F. The more tropical fish like the Amazonian dwelling neon tetras or angelfish prefer warmer temperatures of around 80F 88F. My advice is to always find out from your supplier what specific water parameters (ie. temperature, pH, GH and KH) are required before you get any kind of fish. If your supplier can not give you those parameters then find a better, more informed supplier

Answer 2

Think about it for a minute. Fresh and salt water can be found in the tropics and also in the frozen north and south of the planet. Fish inhabit the waters all over the planet. Therefore there is no specific temperature for all fish. Each species of fish requires water conditions including temperature that are similar to the waters they evolved in.

Answer 3

Most of them range from the high sixties to the low eighties (F). But it depends on the fish living in it, you may want to Google your fish's species and find out what tempature is suitable for them.
