Best Non-Realistic Fish Game: Insaniquarium

PopCap Games

What We Like
  • Four game modes: Adventure, Timed, Challenge, and Virtual Tank

  • Boss battles.

  • Create a personalized aquarium screensaver.

What We Don't Like
  • It's stuck on a lower resolution.

Insaniquarium is from PopCap Games, the makers behind hits like Plants vs. Zombies and Bejeweled. Like those other titles, it's a colorful take on a well-established genre. You tend to your fish to earn coins and jewels used to buy upgrades or egg parts needed to hatch pets with special powers. These pets can even work for you by feeding your fish or protecting against alien threats. If you're looking for a fish game that throws realism out the window, give this one a try.

Old B1ood

What We Like
  • Survival gameplay.

  • You get to be a fish.

What We Don't Like
  • The game never left early access.

  • Multiplayer doesn't always work.

Unlike other games on this list, Feed and Grow: Fish is a survival game where you play a fish who hunts and eats other fish. Doing so lets you grow into larger and larger creatures. It also features a multiplayer component so you can compete with other players to be the dominant aquatic lifeform. Although the game never left Steam Early Access, there's still plenty of things here to enjoy.
