For a tropical fish tank, maintaining a warm environmental temperature ranging between 75 and 80 °F (24 to 27 °C) enables the fish to thrive.

Warm temperatures themselves aren't dangerous to goldfish, but as warm water cannot hold much oxygen, it is best to avoid extreme highs—room temperature is best. While many tropical fish won't work with goldfish for a variety of reasons, there is no reason why some species cannot make suitable tankmates.

In fact, they have a pretty narrow ideal temperature range – the most optimal being 78-80º F (s25. 5-26.5º C). Although betta fish can tolerate temperatures ranging between 72-86º F (22-30º C), if the water is outside of their ideal range, they're just surviving — not thriving.

Best Temperature It depends on the species, but in general, tropical fish are most healthy in the range of 75-80°F (24-27°C). Cool water fish do better in temperatures below that, usually between 60° and 75°F (15-24°C), but some of them enjoy water well below 70°F, which is not suitable for any tropical fish.

A “cold water” fish doesn't specifically require its water to be heated. Goldfish are a prime example of this type of fish. On the flip side, “tropical” or “warm water” fish need their water to be at an optimum temperature to be healthy and comfortable.

To keep plants thriving, the nutrient solution and water solvent must be kept at proper temperatures. Experts agree that the best water temperature for hydroponics is between 65°F and 80°F. This temperature range provides an ideal setting for healthy roots and optimal nutrient absorption.

Temperature: The ideal temperature for a marine tropical fish aquarium is 78-82 degrees Fahrenheit. The ideal temperature for a reef aquarium is 75-78 degrees Fahrenheit.

Ideal Water Temperature for Guppies Guppy fish should be kept in water that's in the 72-82 °F (22-28 °C) temperature range.

There are dozens of species of corydoras, several of which are cold water fish, but the panda cory is the most commonly available one that tolerates lower temperatures. They can survive a range from 65° to 80°.

The difference in water temperature and density congregate the small plankton which attract the bait fish, which then attract the predatory fish. For freshwater fish, especially trout, the optimum temperature is between 45 and 65 degrees Fahrenheit.

Catfish require warm water that's between 74 and 78 degrees Fahrenheit.

A very warm temperature – ensure your tank is heated to 78-82 degrees Fahrenheit. Clean water – betta fish in need of a water change will often lose interest in building bubble nests. The presence of a female (or a strange male) betta fish will also increase the urge for a betta to build a nest.

Check the temperature your African cichlids will need before you bring them home. Tropical fish need warm water that's between 73 and 82 degrees Fahrenheit (23-28 Celsius). Choose an aquarium heater with 5 watts of power for each gallon of water in the aquarium.

Discus Water Requirements Temperature should be kept between 82° and 86° F, although wild Heckel discus prefer water near 90° F. Use an Aqueon Aquarium Heater to maintain proper water temperature.

Salmon Temperature The USDA recommends cooking fish to an internal temperature of 145 degrees F (62.8 degrees C) 1.

In most cases, the high-limit temperature setting on an aquastat should be between 180 and 200 degrees Fahrenheit. If the aquastat is set at 200 degrees Fahrenheit as the high-limit setting and the pressure valve begins to leak, set the temperature back to 195 degrees Fahrenheit.

Turn Down Your Thermostat Usually, when you purchase your tankless water heater you will find that the manufacturer will already have set the thermostat at a temperature of 140 degrees Fahrenheit. That's a common standard. However, for the purposes of most households, there is no need for the temperature to be so high.
