A crowded coral reef with branching red, orange, pink and purple corals and small yellow and orange tropical fish swimming through turquoise water. Dark coral silhouettes and clustered branches in the reef can hide the finder squares, while the many forked coral arms and scattered fish carry the modules. Strong contrast between deep red and navy shapes and the light aqua background keeps the pattern legible. A larger red fish with striped fins on the right gives the scene a clear focal point.
