All of Anissa's friends' marine creatures had turned into mermaids. Some of them had even evolved to develop legs so they could walk on land. But Anissa's acara was still just a fish. She didn't know what to do. She didn't want to lose her friend, but she also didn't want to condemn it to a life of misery.

Anissa decided to take her acara to the ocean. She hoped that the change would happen there and that her acara would be able to live a happy and fulfilling life. She held her breath as she waded into the water and she gently lowered her acara into the waves. The acara swam away, and Anissa watched it go, hoping for the best.

A few days later, Anissa was back at the beach. She was sitting on the sand, watching the waves, when she saw something out of the corner of her eye. It was her acara! It was swimming towards her, and it had changed. It had turned into a beautiful mermaid, with long, flowing hair and a shimmering tail. She wouldn't have been able to recognize it if it weren't for the acara's unique eyes. Anissa was thrilled. She knew that her acara would be happy now and that it would never be lonely again.
