[TOMT] can anyone help me find an old game? I remember you played as a young and fresh marine biologist coming to the beach side to help your father(?) do something

Sorry I played it when I was young and even then I didn't really know why or what I was doing.

Other info I remember is the gameplay is 2D and has actual story, you have to click around to find hidden treasures that blend in the environment. You can use seahorses to show you exactly where an item is if you can't find it.

Once you find all the treasures you sell them for gold which you can use to decorate your very own personal aquarium tank. You can add or upgrade accessories to make your fishes happy.

You also can get trophies once you reached certain milestones, displayed on the menu screen, and you can replay crucial story cutscenes by clicking their disks from the main menu.

(I have a feeling I'm mixing up 2 games that are very similar, or the game I'm talking about simply has 2 versions. Can you help me find them?)
