Clown Killi Fish (Rocket)

Overview

The Clown Killifish / Rocket Killifish (Epiplatys annulatus) is a tiny, surface-dwelling killifish with striking black-and-gold banding. Peaceful and ideal for nano planted tanks with floating cover.

Water Parameters

• Temperature: 22–28°C (72–82°F)
• pH: 5.5–7.0
• Hardness: 2–10 dGH

Tank Setup

• Minimum tank size: 40 litres for 6+
• Decor: Dense planting with floating cover essential; they occupy the surface
• Cover: Tight-fitting lid — they jump

Diet

• Base: Micro flake, crushed granules
• Treats: Micro worms, daphnia, fruit flies (wingless)
• Note: Surface feeder — food must float or sink slowly

Temperament & Tank Mates

• Temperament: Peaceful; males display to each other
• Best companions: Other nano fish, dwarf shrimp, snails
• Avoid: Fish that occupy the same surface zone

Breeding

• Difficulty: Easy; annual killifish — eggs survive drying
• Process: Scatter eggs in peat moss; can be stored damp for months

Common Issues

• Surface dweller — tight lid essential to prevent jumping
• Very small — need appropriately sized food
• Lifespan: 1–2 years (annual species)
