Beauty shows how advanced your aquarium is. You can increase an aquarium's Beauty by buying fish and decorations and placing these within the aquarium. This is something that also earns Stars for your aquarium ⭐

You need Stars to:
- Unlock new aquariums. You need to earn a certain number of Stars in your current aquariums to unlock subsequent ones 🐠
- Receive more coins. Every additional Star gets you bonus coins for the levels you beat 💰
- Earn diamonds or boosters as a one-time bonus. You get them right after you earn new Stars 🚀
