Snack TideEat smaller fish. Grow four sizes. Stay out of Tank's way.

Eat anything smaller. A fish with a red edge is bigger and can eat you, and one in a pulsing red ring is coming for you, so swim away from it. Named fish in the background belong to holders. They swim past without affecting your run. Tank keeps returning, and nobody outgrows him. The longer you survive, the more hunters arrive, the harder they chase, and the sooner Tank returns. A three-second countdown and arrows show which side he's coming from. Leave the dark band between the red edges: he stays in that lane. Later visits can turn back, with another full warning. At full size, the reef's biggest fish hunt you too.

3 lives. Losing one keeps your size but costs half your growth bar. At full size, it drops you back a size. The run ends when you run out of lives. Your prize follows the biggest size you reached, even if you're eaten later.
