"There is so much plankton and different goodies in this sea, but not a single fish! This is strange and completely wrong. Let's fill this sea with fish and see which ones get along best in this place.

Breed fish and upgrade each one in this fun idle game!
Tap on food for the fish to eat! The more well-fed your fish is, the more opportunities it will have for improvement.
Improve not only a fish, but the world around you as welland get more food for the fish. Choose what to improve!

Just look what a wonderful underwater world you can create!"
