What to know before you buy.
The Clown Killifish, or Rocket Killi, is a tiny, surface-dwelling fish with a striking pattern of black and yellow vertical bands and a blue, flame-like tail in males. They are perfect for nano planted tanks and should be kept in small groups. They require tiny, live, or frozen foods due to their small mouths.
