Simple and fun.
Add as many fish as you like.
Feed your fish every day and they will grow soon! Careful, if you don't feed your fish they will die.
Change the decoration and lighting of the tank.
Automatic lighting according to time of day.
Clean your tank with the provided sponge. Aloe will grow if you don't clean it.
Nice bubbles sound.
