''Insaniquarium Deluxe'' is a computer game, created by Flying Bear Entertainment, originally published by Creator/PopCapGames, later taken up by a number of other publishers and based on ''Insaniquarium'', which is similar, albeit simpler. The basic idea: The player runs an aquarium and collects money from ''[[http://www.angryflower.com/pcap/pstrip06.gif cash-pooping]]'' fish while preventing said fish from dying by aliens who randomly invade your tank. There are a number of "pets"; invincible creatures with a variety of functions that can be earned as the player progresses through the many levels in regular mode. In the Virtual Tank, an advanced version of the game, dollars have been replaced with shells, and more features are present: There are a few new pets, fish with different moods, new food items, and fish with special attributes.

!!This game provides examples of:
* AlienInvasion: Subversion: Aliens often pop into the tank and start destroying or eating the player's fish. They don't seem to be in the mood for conquering. And according to their stories, some of the pets' have bad blood with the aliens such as [[BloodKnight Gash]], [[RoaringRampageofRevenge Itchy]] and [[SoleSurvivor Blip]].
* AlliterativeName: Some of the pets have alliterative names, like Stinky the Snail, Meryl the Mermaid, Angie the Angelfish and Stanley the Startlingly Small Sea-Serpent.
* AlluringAnglerfish: Downplayed, as while Gumbo the anglerfish attracts all the guppies with his lure, it is only to lead them away from their alien predators.
* AnimalGenderBender: Gumbo the anglerfish is described as "he" despite having female-specific characteristics such as size and shape.
* AnimalsNotToScale: Because all of the pets are roughly the same size, some pets can be really small compared to the animal they're based on, like Wadsworth the Whale and Brinkley the Elephant. Lampshaded with Stanley the Startlingly Small Sea-Serpent.
* ArtisticLicenseAnimalCare: Gumbo is a deep-sea anglerfish (illuminated esca rather than one which looks like a worm) and could not survive anywhere near the surface, much less in an aquarium. Also, the bioluminescence of a deep-sea anglerfish's esca is due to bacteria; it cannot be switched on or off.
* BackFromTheDead: The basis of Angie the Angelfish's powers.
* BigBad: [[spoiler: Cyrax]]
* BioluminescenceIsCool: Gumbo the anglerfish, or at any rate his -- er, her esca.
* BreadEggsBreadedEggs: Stanley, one of the bonus pets, is afraid of nothing but badgers, aprons and badgers wearing aprons.
* CarnivoreConfusion: Partially Averted with Virtual Tank Store-bought Carnivores, Guppycrunchers, and Ultravores
* CatSmile: The Star Catcher.
* DanceBattler: [[spoiler: Rufus the Fiddler Crab was a dance instructor until his studio was destroyed in a freak accident. He becomes a [[PrivateMilitaryContractors mercenary for hire]] while still retaining his dancing skills.]]
* DeadEndRoom / UnwinnableByInsanity: [[http://insaniquarium.wikia.com/wiki/Tank_6_%28Glitch%29 The Tank 6 Glitch]].
* DeathByGluttony: Gus is an alien then is [[ImmuneToBullets immune to lasers]]. Thankfully, he loves to eat! Enough to gobble all the food the player gives him. Until he ''explodes''.
* DemBones: [[DarkIsNotEvil Vert the Skeleton]] and Bilaterus.
* EliteMooks: Every alien beyond [[ThoseTwoBadGuys Sylvester and Balrog]]. All have distinct roars, distinct [[BossWarningSiren signatures]], and need a little more strategy to defeat beyond "shoot until dead".
** Gus is immune to laser fire, and has to be fed with fish food until he explodes.
** Destructoid stays at the bottom of the tank and fires missiles that need to be shot down.
** Psychosquid occasionally turns blue and passive, and will regain health if shot.
** Ulysses fights similarly to Destructoid, except he fires energy balls that need to be reflected back at him.
** Both of Bilaterus's heads must be destroyed to kill him.
* EnemyMine: [[spoiler:Itchy and Gash will work together to kill aliens, despite Gash wanting Itchy mounted on his wall. They were actually once friends but Itchy abandoned Gash. As a result, Gash became a tweener at most]].
* EnemySummoner: [[spoiler:The final boss, Cyrax, can summon all the other aliens during its fight.]]
* EverythingsBetterWithPenguins: Walter the Penguin is the last bonus pet of the game. His power? Making fishes drop money and other pets use their powers by punching them... with a boxing glove that is '''''hidden in his mouth!!!'''''
* EverythingsSquishierWithCephalopods: Psychosquid, a, well, [[ShapedLikeItself squid.]]
* FishOutOfWater: Inverted. Brinkley is an elephant who lives in water, wearing a snorkel mask.
* FlameWar: [[spoiler:In-universe example, apparently flame wars have been fought over which of Bilaterus' heads controls him.]]
* GameMod: Different songs, different food colors, and more.
* GagNose: Nostradamus, one of the bonus pets, is a disembodied nose with fins. Which can sneeze to postpone alien attacks. And also drops 1$-worth snots.
* GravityMaster: Seymour the Turtle slows down the fall of coins and food in your tank, allowing pets and fish to collect them more easily.
* HitPoints: The aliens' hit points can be seen when Blip is in the tank.
* ImmuneToBullets: Gus is the only alien that can't be hurt by lasers at all [[spoiler:(except during the final fight)]].
* InvoluntaryShapeshifting: Presto the Tadpole can be right-clicked to make him metamorph into any of the other pets you have.
* KonamiCode: Used to unlock [[spoiler:Sandbox Mode]].
* OurMermaidsAreDifferent
** Meryl is a former well-known pop star; when she sings, the fish briefly drop more coins.
** Balrog is a hostile alien merman who attacks you along with other aliens.
* MookChivalry: Apparently, Ulysses, the type-U alien, [[spoiler: can shoot already-lasered energy balls if he wants to, but he doesn't due to an honor code that all cyclopes share. Also, he's dumb.]]
* MotherOfAThousandYoung: Prego the Mother Fish, a benign version of this trope.
* MrViceGuy: [[spoiler: Stinky the Snail, who picks up falling coins for you, knew early on that he was a miser. Clyde, [[TheDutifulSon on the other hand,]] collects money for his mother's operation.]]
* PerplexingPearlProduction: Niko the oyster creates a pearl every few minutes. Each one yields a ''lot'' of money.
* PsychicPowers: Blip opens buying options and reveals when fish are hungry, when aliens are about to attack, and aliens' hit-points. [[spoiler:He was also able to sense a bad feeling at the bottom of a tank; [[AllOfTheOtherReindeer the other fish in the tank were jerks to him]], though, and so he didn't bother telling. Then, an alien came and ate all the fish. [[SurvivorsGuilt Blip felt guilty after that and vow that he will only use his powers for the benefit of everyone.]]]]
* PsychoElectricEel: Amp is a pet electric eel which can zap all the guppies in a tank in order to turn them all into diamonds.
* RidiculouslyCuteCritter: Many, but especially the ''adorable'' Star Catchers.
* RoaringRampageOfRevenge: [[spoiler: Itchy wasn't actually an alien-despising warrior before. But his friends were devoured by an alien, so Itchy seeks to murder every alien in existence.]]
* TheScrappy[[invoked]]: In-universe example. [[spoiler: Rhubarb is considered the worst pet in the game. However, Rhubarb isn't really for the attention, he just hates when fish are at the bottom of the tank.]]
* ShoutOut: One species of alien is called 'Balrog', a reference to the Creator/JRRTolkien's evil [[Literature/TheLordOfTheRings humanoids]] [[Literature/TheHobbit from]] [[Literature/TheSilmarillion Middle-earth]]. Another, Sylvester, looks like the Alien from... well... ''Franchise/{{Alien}}''
* SolidGoldPoop: The various fishes "produce" a wide range of valuables, including coins, pearls, diamonds and '''''treasure chests'''''.
* SpiritualSuccessor: ''VideoGame/PlantsVsZombies'', which was [[http://arstechnica.com/gaming/news/2010/03/george-fan-how-insaniquarium-2-became-plants-vs-zombies.ars originally envisioned as a sequel]].
* StalkerWithACrush: [[spoiler: [=PsychoSquid=]'s girlfriend gave him that nickname when, after their break-up, he kept calling her and waiting at her door.]]
* StockSoundEffect: [=PsychoSquid=] uses the T.Rex roar from ''Film/JurassicPark.''
* SwallowedWhole: Wadsworth the Whale does this to your smaller fishes to protect them during alien attacks.
* TheUsualAdversaries: The aliens. They constantly warp into your tank with the sole purpose of eating/killing your fish, and don't stop coming until everything in the tank is dead. Most of them don't have a reason for why they're doing this beyond being evil space-aliens. Apparently, their rampage isn't a new thing, as they figure into the backstories of several of your pets.
* WeUsedToBeFriends: [[spoiler: Gash and Itchy used to be best friends, until the latter left him for dead. Gash swears to settle his score with Itchy.]]
* WidgetSeries: Let's just say that there's a reason why it's called ''Insani''quarium.
