The best temperature for your fishy friends depends on the species, but in general, tropical fish are most healthy in the range of 24-27°C. Cool water fish do better in temperatures below that, usually between 15-24°C, but some of them enjoy water well below 15°C, which is not suitable for any tropical fish. The best temperature will depend on the species of fish in the aquarium. Research the fish you are interested in keeping before setting up an aquarium and only chose those that have similar temperature and water quality requirements. Use of a dependable heater, and thermometer like the Juwel Heater Aquarium 300w will assist you keep the correct parameters for your fish. You should check the water temperature regularly to ensure frequent or large temperature changes don’t occur. As with most factors in aquarium keeping, large sudden changes in any parameter can result in disease and death of your fish.
Most fish require specific temperature ranges when breeding which is usually higher than the normal temperature they require. In some cases; like Goldfish, breeding is triggered by a drop in temperature. When breeding fish, it is important to know the water temperature requirements of the species being spawned so that the temperature can be manipulated in a separate breeding aquarium to meet their needs.
Introducing new fish
It is important when introducing new fish to your aquarium that you are aware of the temperature in your tank as well as the temperature of fish in the little bag you have brought home from your LFS. Temperature shock is one of the biggest causes of sudden fish death. It is easily avoided by ensuring your aquarium is in the correct temperature range for the species you are keeping; and that you acclimate your fish before placing them into their new home.
