Strategy

 * Use the rocket to reach small fish and escape from big fish. Use it wisely because the Rocket is expensive.


 * After reaching your first evolution, you can perform an advanced, but risky trick with Blue Whale's rocket booster. If you split just after your last rocket boost ends, the momentem from your rocket boost will be carried over into your split, causing you to split much faster and farther then is usually possible for other fish (this trick can also be performed by the Dolphin of course). You can use this trick to close a considerable distance between you and a potential meal very quickly, but it's also quite risky because the increased speed and distance of your split could cause you to split straight into a nearby bigger fish or electric mine, and you lose all directional control while splittng.
