Degrees Centigrade.
The instrument that is needed to measure the temperature of the water is called an "Aquarium Thermometer".
If the fish does not struggle (it would have to be dead not to) and above water, then you can measure a spring scale.
the fish tank
The most reasonable unit to measure a fish pond would be square meters or square feet. This unit of measurement provides an accurate representation of the area of the pond, which is important for managing stocking densities and planning fish production.

I believe fishes blood temperature would be the same as the water it resides in .
fish tank
The body temperature of a fish swimming around in water that is 60 degrees would be 60 degrees also. This is because fish, unlike mammals, are coldblooded; they do not waste energy keeping their body temperature constant. Their body temperature would match that of the water around them.
Fish are cold blooded. so all you have to do is stick the therrmometer inthe water it is cept in.
a meter stick.
