Abyssrium World: Tap Tap Fish for Android

The player has to build something like an ocean city for fish, although in fact the gameplay is more like a landscape design. Having built something beautiful, you can relax and watch different sea creatures with relaxing music.

The range of appearing underwater inhabitants is very large, from small fish and jellyfish to whales. Stones, corals, sea-weeds, and various statues can be used in construction. The online functionality allows you to see what other players have built.
