Millimeters may be appropriate, or perhaps centimeters. If a fish is 63 mm long, then it would be 6.3 cm long. U have to take the fish out of the aquarium

It really depends on how small the fish is. If it is very very small, then grams (or even milligrams). If it is medium size, then grams. If it is large, then kilograms. It all really depends on how accurate you want to be.
The SI unit for mass is the kilogram. When massing a fish or any other substance for calculation the use of the kilogram unit will not require changing units as opposed to Imperial measurements.

If the fish does not struggle (it would have to be dead not to) and above water, then you can measure a spring scale.
