Here is the schematic for the Aquarium car.

The first item to check is that all wiring is intact from the rollers.

The next item to check is the on/off switch. Jump the switch out and see if the car works. Next in line is the 10 ohm, 2 watt resistor connected to the red wires. If that checks OK, chances are the circuit board is history.

The parts layout and numbers is here.

I'm told that the fish we buy from Asia is not up to par with the fish they buy from us.  True fact.  So no wonder your fish seem DOA.....LOL
