Build your aquarium. Keep the aliens out.

Finsanity is an aquarium arcade game where you raise colorful fish, collect coins and treasure, and defend your tank from hungry alien invaders. Keep your fish fed, spend your earnings wisely, and recruit peculiar pets with unique abilities and strange habits.

There’s more to running an aquarium than sprinkling in some food. Treasure is falling, your fish are hungry, and something with far too many teeth just appeared in the tank. You’ll need quick clicks and smart decisions to keep everyone swimming.

Raise Your Fish

Fill your aquarium with colorful creatures and keep their appetites satisfied. Collect the rewards they drop and put your earnings toward new fish, better food, and upgrades.

Fight Off Alien Invaders

When unwelcome visitors arrive, your fish are on the menu. Click to fight back, upgrade your weapons, and protect your aquarium without neglecting its hungry residents.

Meet Some Very Peculiar Pets

Bring along unusual companions with special abilities and personalities of their own. Some make life easier. Others have a funny way of helping.

Keep Up With the Chaos

Balance feeding, collecting, spending, and defending in a tank that demands your attention. Simple point-and-click controls put you in charge. Keeping everything alive is the tricky part.
