Finding Cleo

Cleo is hiding in the aquariums. Can you find every fish?

Finding Cleo is a calm logic puzzle about fish, water, and careful deduction. Each connected tank contains exactly one fish, and fish can never touch—not even diagonally. Use the row and column clues, adjust each tank’s water level, and discover where Cleo and her friends are swimming.
