Insaniquarium

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. These pets can help you feed your fish, collect coins, or even protect against the aliens that will invade your tank and wreak havoc. You can also use the money you earn to buy better weapons to see the aliens off quicker!

Insaniquarium Deluxe includes 3 fun ways to play:
Adventure - keep your fish healthy and protect them from aliens through 4 fun aquarium stages each with multiple levels of mayhem
Time Trial - feed your fish and fight off the alien invaders to make as much money as possible against the clock. A new time trial is unlocked as you complete each stage in Adventure
Challenge - once you've mastered Adventure, face the ultimate challenge as you feed your fish and try to protect them from ever increasing alien attacks. The challenge ends when the last fish is zapped!Insaniquarium (or Insaniquarium Deluxe) is a challenging game that features a virtual water tank. The aim of this game is to look after a number of fishes, which will increase as we play along. We must feed all the fishes, collect the falling coins and shells before they touch the bottom of the tank, use the collected money to buy food, improve the food quality, buy more fishes and egg pieces, get bonuses, and most importantly, buy weapons to fight the enemies that will appear on the scene trying to eat our pets. All these tasks must be done at the same time, so that we must be very quick and alert if we wish to go to the next level (although I myself seldom managed to do so, as the increasingly demanding aquarium almost drove me mad before I got anywhere).

The game is divided into three playing modes: Adventure, Time Trial, and Challenge. A peculiar feature is that we can use the virtual tank as a screensaver. In this mode, it will be still working, so we must fill the tank with the correct bonus pets that will collect the money and feed the fishes for us. There are a lot of customization options: naming the fishes, choosing whether to show when they are hungry or not, etc. We are free to play the game for 60 minutes. This game runs under Windows Vista, XP, and 2000 operating systems.
