Pets
After you beat Tank 4, you will be given the following Pets:
- Tank 4-1 - Nimbus The Manta Ray is a white manta ray which tosses up coins and fish food up to the top of the tank. Price: $9000
- Tank 4-2 - Amp The Electric Eel can electrocute your tank which kills all your guppies in exchange for Diamonds. Price: $75000
- 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 4-4 - Angie The Angelfish can revive dead fishes, but only if the corpse is still there. Price: $225000
- 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 upon the completion of a 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 pretty much 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.
