The watermelon puzzle Fish Merge offers you to manipulate not fruits, but with fish. Dropping fish into the water, strive to ensure that pairs of identical individuals collide and merge, getting a new type of fish. The water level will gradually rise as the aquarium is filled with fish. But you should not allow the number of fish to become too large by filling out the failure of the entire glass container in Fish Merge. Try to create all types of fish, filling them with a scale in the lower screen of the screen.
