''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.
* BackFromTheDead: The basis of Angie the Angelfish's powers.
* BigBad: [[spoiler: Cyrax]]
* 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.
* DeadEndRoom / UnwinnableByInsanity: [[http://insaniquarium.wikia.com/wiki/Tank_6_%28Glitch%29 The Tank 6 Glitch]].
* DemBones: [[DarkIsNotEvil Vert the Skeleton]] and Bilaterus.
* 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.
* HitPoints: The aliens' hit points can be seen when Blip is in the tank.
* OurMermaidsAreDifferent: Meryl is a former well-known pop star; when she sings, the fish drop coins.
** Balrog is a hostile alien merman who attacks your along with other aliens.
* MookChivalry[=/=]GenreBlindness: Apparently, Ulysses, the type-U alien, can shoot already-lasered energy balls if he wants to, but he doesn't due to an honor code that all cyclopes share, and he's dumb.
* MrViceGuy: Stinky the Snail, who picks up falling coins for you, knew early on that he was a miser. Clyde, on the other hand, collects money for his mother's operation.
* 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.]]
* ShoutOut: One species of alien is called 'Balrog', a reference to the J.R.R. Tolkien's evil [[Literature/TheLordOfTheRings humanoids]] [[Literature/TheHobbit from]] [[Literature/TheSilmarillion Middle-earth]].
** Another, Sylvester, looks like the Alien from... well... ''Franchise/{{Alien}}''
* 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: [=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.''
* WidgetSeries: Let's just say that there's a reason why it's called ''Insani''quarium.
