To start off, you will have a couple of guppies. You will need to feed and take care of their health. Click on the tank to dispense food or medicine. As the guppies eat, they will get bigger and drop silver and gold coins.

In addition to feeding fish, the fish must be protected by the participant from aliens who occasionally go into the tank and attempt to consume the fish. The aliens must be clicked repeatedly with the mouse pointer to defeat them. The deluxe version of Insaniquarium comprises nine different aliens, but you will find four. Insaniquarium Deluxe is the craziest aquarium game ever – tend to your fish and keep them happy and they’ll reward you with precious coins and jewels. Use the money you earn to buy upgrades for your tank or egg parts which hatch lots of different in-tank pets with special powers.
