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 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 .
most fish tanks are measured in gallons unless it is more of a small fish bowl instead

A scientist would typically use a ruler or measuring tape to measure the length of a fish. They would place the measuring tool along the fish from the tip of its mouth to the end of its tail to get an accurate measurement.
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.
