It is not likely because most trophy fish can weigh several hundred pounds and most post offices scales max out at a mucher lower weight. Typically hanging scales are used for large trophy fish.
The largest fish in the world is the whale shark, which can weigh over 70 thousand pounds. Another large fish is the basking shark, which are over 5 thousand pounds.
The weight of a fish can vary widely depending on the species. For example, a small goldfish may weigh around 100 grams (0.1 kg), while a large tuna can weigh over 200 kg (200,000 grams). On average, freshwater fish like bass or trout typically weigh between 1 to 5 kg (1,000 to 5,000 grams). Thus, the weight of a fish can range dramatically based on its type and size.

It really depends on the fish.
A fish which happens to be particularly large.
That depends on the weight of the fish as compared to the weight of the water their bodies displace. If it's a heavy, dense fish, then the tank with the fish would weigh more. If it's a light, less dense fish, then the tank with water only would weigh more. This assumes that the water displaced has been removed from the tank, right? If you are adding the fish to the water then I think it should increase the weight regardless of the density of your fish. The question then might be, does the fish weigh less when it is swimming than it would on a dry scale?
