Keep My Tank

A one-time upgrade that turns your aquarium into a keepsake. It stays forever, and every theme unlocks.

What you get

• Your tank, forever. Free aquariums disappear after 24 hours. A kept tank stays put so you can come back to it any time.
• Every theme unlocked. Swap your aquarium between all the backgrounds: kelp forest, coral reef, the deep, night, outer space, and more.
• Keep adding creatures. You can keep drawing and scanning new sea creatures into the same tank.
• A private link to your tank. Revisit and manage it whenever you like.

How it works

Create an aquarium, then draw and scan your sea creatures. When you want to keep it, open the tank's settings and choose Keep My Tank. Pay once, and that aquarium is yours to keep.

The fine print
