Fish are cold blooded animals and rely on the temperature of the water for their heat. There are some fish (Tuna) that are reported to have a method of heating their bodies above ambient temperature by extreme exertion.

How small can a fish tank be with it still being tropical?

That all depends on how warm the area is where you wish to keep the tank. If the tank will need a heater/thermostat unit then that would be the main physical limiting factor. The unit must go completely under water. I would remind you however that the smaller the tank the harder it is to keep fish in it successfully. The basic rule for keeping fish is 1 gal (4.25ltrs) of water is needed for 1" (2.5cm) of fish.
