Forktail Blue Eye Rainbowfish
Forktail Blue Eye Rainbowfish (Pseudomugil furcatus) – Active, Vibrant Nano Fish for Planted Aquariums
The Forktail Blue Eye Rainbowfish, Pseudomugil furcatus, is a striking nano schooling fish known for its vivid electric blue eyes, translucent yellow fins, and signature forked tail. These energetic swimmers bring sparkle and constant motion to planted or community tanks, especially when kept in groups of six or more.
Native to Papua New Guinea and now tank-raised for aquarium trade, Forktails thrive in soft, slightly acidic to neutral water with gentle flow and lush plant cover. Their peaceful temperament and small size make them ideal tankmates for shrimp, pygmy corydoras, and other micro fish.
