what temperature is appropriate for tropical fish
Tropical fish are those that require heated water, generally in the range of 75-80Â°F (24-27Â°C). Because many homes are not kept in that temperature range day and night, these fish require a heated aquarium.old water fish do better in temperatures well below that, some of them enjoy water well below 70Â°F, which is not suitable for any tropical fish. Ultimately the best temperature will depend on the species of fish in the aquarium.
