Temperature fluctuations often go unnoticed by aquarium hobbyists and can result in fish and stress or even death. It is therefore necessary to purchase a quality to ensure that your freshwater tank or reef aquarium remains within ideal temperature ranges for livestock as well as to monitor your tank temperature regularly.

Before you add the new water to the aquarium, ensure that match the temperature and water parameters of the existing fish tank water

Most include a built-in thermostat to select the optimal temperature for your tank. However, you should still use an so you can quickly and easily monitor the water temperature. A can turn aquarium heaters off if they get stuck on to prevent overheating as well as keep aquarium chillers and fish tank heaters from running at the same time to save electricity.

Place the thermometer in/on the tank

for those of you with normal tropical fish, what temperature do you keep your tank at? i just keep mine at 78F. The Red Shiner is a very active temperate fish that must be kept in shoals of at least 5 of their own kind. They are active swimming fish so require a very long wide tank, a minimum of 88.9cm (35") in length, to allow for this movement. They should never be housed with slower moving fish like as the Red Shiners are known to fin nip. They can work with other faster swimming fish like . Their tank should be well oxygenated with good surface movement. These are an attractive alternative to common coldwater fish, the males are iridescent blue/green and red in colour, the females have less to no red and just iridescent blue/green flanks with hints of red in the fins. The vibrant nature of their colours will show best under excellent aquarium lighting and they can look dull in shops.

What temp does a cold water tank have to be ..

So, I’m going to put my oscar fish in this new 40 gal tank because he is out growing the 20 gal tank. So I am thinking, what type of heater should I get for my oscar fish so it the temperature reaches 26c/79f?

I can't think of any common aquarium COLD water fish off hand.

I’ve had my guppy tank for a couple months now. I’ve successfully gotten by with NO heater for my aquarium. What water temperature do guppy fish need? I didn’t think they needed heated water but I could be wrong. Tank details: 10 gallon aquarium with 5 guppies. They seem somewhat different lately.. Maybe I’m over thinking this. Could use advice.:
Guppies are from tropical climates so your tank needs to be of tropical temperatures. You need a temp of 75-80 degrees Fahrenheit. It’s very important to have the correct water temperature for tropical fish. You may be able to hold down that water temperature if you live somewhere with warm weather. If you need to buy a heater, figure on needing 5 watts for every 1 gallon of water in your aquarium. You said your tank is 5 gal so that means you need a 25 watt aquarium heater.
