Once upon a time, in a beautiful crystal clear lake nestled in the heart of the forest, there lived three fish: Goldie the goldfish, Silver the silverfish, and Sapphire the sapphire fish.
Goldie was the oldest and wisest of the three. She had lived in the lake for as long as anyone could remember, and had seen all sorts of things in her long life. Silver was the middle fish, and was a little bit of a troublemaker. She loved nothing more than swimming through the reeds and playing hide and seek with her friends. Sapphire was the youngest and smallest of the three, and was always eager to learn and explore.
Every day, the three fish would swim and play in the cool, clear water of the lake, darting in and out of the reeds and chasing each other through the sparkling waves. They were the happiest fish in the whole lake, and everyone who saw them swimming about would stop and watch in amazement at their grace and beauty.
But one day, a strange and fearsome creature came to the lake. It was a giant, fierce-looking catfish, with sharp teeth and a scaly, slippery body. As soon as it saw the three fish, it began to chase them through the water, determined to catch them and make them its dinner.
Goldie, Silver, and Sapphire swam as fast as they could, darting and weaving through the water in a desperate attempt to escape. But the catfish was too fast, and it seemed that there was no way they could outswim it.
Just when all hope seemed lost, Goldie had an idea. She called out to her friends and told them to swim down to the very bottom of the lake, where the water was dark and cold. The catfish would never be able to see them there, she said, and they would be safe.
So the three fish darted down to the bottom of the lake, and hid amongst the rocks and weeds, panting and gasping for air. The catfish swam around above them, searching and searching, but it could not see the three friends hiding below.
Finally, after what seemed like an eternity, the catfish gave up and swam away, leaving the three fish safe and sound. From that day on, they were extra careful whenever they swam about in the lake, always staying on the lookout for any more fearsome creatures that might want to make them their dinner.
But for the most part, life in the lake was peaceful and happy, and the three fish spent their days swimming and playing and having the time of their lives. And at bedtime, they would snuggle up in a cozy little bed of seaweed, and drift off to sleep, dreaming of all the adventures they would have the next day.
