Overview

Clown Killifish, also known as Rocket Killifish, are one of the most eye-catching nano fish available. With bold vertical stripes and a vivid red tail that looks like a rocket flame, these tiny surface-dwelling fish bring constant movement and color to planted nano tanks.

Peaceful, hardy, and full of personality, Clown Killifish are perfect for aquascapes, shrimp tanks, and calm community setups. They prefer to cruise near the water surface, making them a unique focal point even in smaller aquariums.

Why you’ll love them:

  • Stunning rocket-style red tail & striped body

  • Perfect for nano tanks (5–10 gallons+)

  • Peaceful and shrimp-safe

  • Active, curious, and fun to watch

  • Great choice for planted and blackwater tanks
