Tank 4 Backdrop

Tank 4 is the hardest tank in all of Insaniquarium. Guppies are harder to get. Prices have increased dramatically. Do you have what it takes to finish this tank?

Music

Pets

After you beat Tank 4, you will be given the following Pets:


  • Tank 4-3 - Gash The Shark is an orange shark who deals the most damage to aliens, but will eat one of your guppies from time to time. Price: $150000
  • Tank 4-5 - Cyrax The Evil Alien Mastermind is the leader of the aliens who have been attacking your aquarium. He's not really a pet, and in order to get the final egg, the player is forced to defeat him after completing the level. Price: $299997

Aliens

Bilaterus - an alien with two heads. Both heads must be defeated to truly defeat Bilaterus.

Fishes

Breeder - the only way to get guppies is by taking care of a breeder. Once she grows into her medium size, she gains the ability to give birth to baby guppies, just like Prego. Price: $200

Carnivore - this fish returns from Tank 1 and behaves pretty much the same as it was in that tank. Price: $1000

Ultravore - a large fish which drops Treasure Chests and eats Carnivores. Each treasure chest gives the player $2000. This fish is the key to buy the very expensive egg pieces of Tank 4, though due to its large size, it is the most vulnerable to aliens. Price: $10000

Trivia

  • In Tank 4-4, as the first Destructor + Ulysses combo approaches, the alert ticker which would normally say, "Multiple Alien Signatures Detected" but it will instead say, "Fourteen Alien Signatures Detected" and after a few seconds switch to "Just kidding, only two!"
  • $99999 is the highest price that can fit on the price tag. Anything over 6 digits cannot fit. So the egg is basically $300000 - 3.
  • It is a good idea to use Ultravores and some money collecting pets, since the prices of the egg pieces can be quite expensive in this tank, especially tank 4-5, where the egg pieces are $99999.
  • Another good idea is to keep at least a maximum of three Breeders, as to not overwhelm yourself with guppies while preparing to get Carnivores.
