The air hummed with a restless energy within Daniel as he considered the prospect. A goldfish. Simple, low-maintenance, and oh-so-charming! He started pacing, a broad smile plastered across his face.

“Think of it, Ethan! A little fishy friend! We can name him…Captain Bubbles!” Daniel imagined himself leaning over the bowl, whispering secrets to the shimmering scales.

Ethan, engrossed in his book, merely sighed. “Daniel, we're barely able to keep the plants alive. A goldfish is another mouth to feed, another responsibility.”

Daniel spun around, doing a mock-serious salute. “We can make a whole underwater world! With little castles and treasure chests! And we can watch TV with our friend!” He even pretended to make a fish swim with his hand.
