Fisch mich

Big and small anglers meet at the tin pond for the yearly angling competition. Even Andrew Angler is wielding his fishing rod.
Suddenly a green fish finger turns up and yells "Fish for me!" Andrew Angler rubs his eyes. There! A second fish finger and a red pufferfish swim toward him chorusing "Catch me! Catch me!"
But unfortunately Andrew Angler may only catch yellow fish in this angling round. So he has to be careful: as if he gets close to a wrong fish ... snap! The fish will be clinging to his fishing rod.

Who, with some skill and a bit of luck, will catch the most fish?
