Event conveyor.
Prioritize it over a lower percent fish when it appears, then confirm you still have a flat anchor.
Fish come out of a tunnel and travel a river conveyor. Press E to buy one with cash. It walks to an empty pad in your house and generates cash every second. Step on the green floor button to claim that cash. Other players can carry a fish away if your force field is down and the fish is not Unstealable.
Written guides current through October 19, 2026 say a rebirth removes only the cash and the exact fish named on that level. The rest of the aquarium stays. One July 2025 play video described a wider loss of stolen fish, so confirm the checklist on the Rebirth button before you confirm.
A percent fish pays a share of your single best flat-income fish. Hungry Deer is listed at 150 percent, The Moon at 160 percent, and Cthulhu at 250 percent. If that flat anchor is sold, stored in the vault, or stolen, every percent fish drops with it.
The Fish Vault is on the top floor after a late rebirth. Fish inside cannot be stolen, and they also stop generating cash. Use it for rebirth ingredients and prizes, and leave your best flat earner on a normal pad.
