Have you ever wonder that in the natural, how do the fish live without a heater?
So why do we need to keep our aquarium at a constant temperature?
It is due to how fast the temperature changes. In the wild, with so much amount of water, it will take a long time (a day or even a season) for the temperature to go down or rise up, long enough for the fish to get in the swing of changing water.
On the contrary, the aquarium habitat, with a much smaller amount of water, the temperature rapid swings and causes the problems. This is the reason why you will need the best thermometer for fish tank to maintain water temperature.
What happens if the water temperature is too high/low?
When the water is too cold it will affect your fish’s metabolism, this process will slow down, and your fish are slow and sluggish too, especially with the topical fish.
In the case of water is too warm (when it reaches 90 F degrees and more). The metabolism process becomes faster and your fish are more active than normal. But when it happened, it causes the risk of shortage of oxygen because warm water contains less oxygen than cold water. Do not enough oxygen your fish can suffocate.
The changing quickly of temperature can also increase the risk of stress for the fish and lead to the weakness of the fish immune system. And the dead become possible for your fish.
Due to these reasons up to here, it is so important to have the best aquarium thermometers to help you maintain and monitor your aquarium water.
What is the ideal temperature that you should maintain in your aquarium?
Each type of fish requests their own temperature and also have different stiff upper lip levels of temperature swings.
Coldwater fish requests an ideal temperature below 68 F degrees (20 C degrees).
Tropical fish request ideal temperature from 75 to 80 F degrees (24-27 C degrees).
Temperate fish have a wider range of temperature than others that mean they are easier to keep.
