Yes it is important to have a thermometer in your fish tank. The temperature of the water should be between 75-80 degrees.
Mercury is common in both fish and thermometers. Although nowadays they make thermometers without mercury in them.
you have to make shure that the tank is clean and ate the right tempiter or you will kill the fish
The sticker type thermometers are not very accurate and tend to be affected by external temperatures. To better monitor your tank water temperature, you can buy a thermometer that sticks on the inside with suction cups
mercury is used in thermometers
If a fish tank is filled completely, then anything added to the tank will cause it to overflow, and any disturbance, which might result from the vibrations of a passing truck, will cause it to overflow; in addition, there is an increased risk that some foolish fish might leap out of the tank.
Hold the fish down and throw out of tank
it depends on how big it is if it is a goldfish or beta it can be in a bowl.If it is one of those big tiger fish or aqarium fish then put it in a big tank. A fish will grow to the size of the tank or bowl. For instance, say a goldfish is in a tank, it will not grow as big as the tank; however it will grow big enough to be able to swim in their environment. The fish will not overgrow the tank. I had a six inch goldfish in a thirty gallon tank.
That depends on what you mean to say. For example, if you have one angel fish in the tank you could say "That's the fish's tank" meaning that is the tank for the angel fish. If you also had a couple of clown fish, you could refer to the tank as belonging to all three fish by saying "That's the fishes' tank." Slightly different spelling and punctuation
Yes, but depending on how big you or the tank is.
Thermometers are devices which can be used to measure the body temperature. The body temperature is an important health indicator, and to assess it properly the core temperature must be measured. The best way to this is through a rectal or aural measurement - these require specific thermometers. Aural measurements are most common in professional settings because of their reliability and ease of use, though a rectal measurement is still the most accurate. Nowadays most thermometers are electric, for greater accuracy and safety. Mercury thermometers are no longer used in medical applications, due to the toxicity of mercury, and many countries have banned the classic mercury-in-glass thermometers from such purposes.
Not in its self. The fish could jump out of the tank and land outside the tank, though.
In my research when there are more Panda Corys in a tank the activity of the fish is increased. The fish will move in groups when there are multiple fish. The one alone has the average speed extrmely less then the tank with two fish and the tank with three fish.
