• Schooling: Never keep alone; stress increases without a school.

• Temperature: Avoid rapid temperature fluctuations.

Fun Fact

Neon tetras’ brilliant colors come from iridophores—specialized cells that reflect light, creating their glowing neon effect, especially visible in dim or blue lighting.
