Difficulty: Moderately Easy
Step1
Download Insaniquarium. There are 2 sites listed in the Resources section that are safe to download from.
Step2
Open the game and click on Adventure. There are 4 different game modes but you must start with the adventure and complete the tasks there before you can play the Time Trial or Challenge modes. The Virtual Tank is not actually a game.
Step3
Feed your fish. When the tank opens, you will have two fish and you must feed them in order for them to grow. As they grow, they will drop coins, which you collect to increase your funds, so you can buy more fish or egg pieces. Each tank has five levels. When you complete a tank, it is then available for you to play in Time Trial. The Challenge mode only becomes available when you have completed all of the Adventure.
Step4
Buy items. Multiple items will appear as your money increases. Among them is fish, food, weapons and egg pieces. When you have bought three egg pieces, the level will be complete and the egg will open to show a new pet. Each pet has a special feature that can help you throughout the game. You may only use three pets per level so choose wisely.
Step5
Fight aliens when they appear. There are certain strategies to fighting aliens so they don't destroy your fish. Normally you will click on them to deflect them in the opposite direction. However, some aliens do not respond to your lasers and you have to figure a different way to destroy them.
Step6
Keep your fish happy and healthy. If you don't feed your fish or protect them from the aliens then they will die and the game will be over.
