A 100-gallon fish tank weighs approximately 834 pounds when filled with water. The weight of the tank itself can vary depending on the material it is made of, but the water alone would weigh around 8.35 pounds per gallon.
That all depends on how big the fish are. The rule is "1 inch of fish needs a minimum of 1 gallon of water". The tank could easilly be overcrowded if it is stocked with large cichlids and understocked (if there is such a thing) if the fish are Neon Tetras.
A 1 gallon tank could have one betta fish, but you will need to be diligent about changing the water on a regular basis. The smallest tank that should be used, even for a betta, is a 2.5 gallon tank as it at least gives the fish swimming room.
