Two ways to say "colourful fish" (for a 7-year-old)
- Rainbow fish
What it means: A fish that looks like a tiny rainbow because it has lots of bright colors.
When to use: Use this when you want a short, fun name. - Fish with lots of pretty colors
What it means: A simple sentence that says the fish has many pretty colors.
When to use: Use this when you want to describe the fish clearly and simply.
Both say the same idea—the fish has many colors—but one is playful and short, and the other is clear and full.
