The Forktail Blue-eye (Pseudomugil furcatus) is a moderate-care, peaceful species from Papua New Guinea. Adults reach roughly 1.6", so plan on a minimum tank of 10 gallons. Keep the water between 72–82°F with a pH of 6.5–8. This is a schooling fish — keep a group of at least 6 so it feels secure and colors up. Its long fins make it a target for known fin-nippers. As a micropredator, it does best on a varied diet appropriate to its feeding style.
