Start with a friendly fish that eats plankton, but then as you grow, you can hunt toothy predators. There are two variants of the game, this is a walkthrough and a survival arcade. In the passage mode, the progress of the growth of the fish is preserved, and more dangerous predators appear.

1. Collect plankton floating in the water by clicking on the screen or on the left mouse button on the screen. If the fish has become a predator, eat other fish below the class. Click on the character icon, here you can see which fish you can eat.
2. The winner is the one who eats the required amount of food faster. See the account status, next to the icon. Each level has its own final result.
