Pseudomugil furcatus

Pseudomugil furcatus is a small rainbowfish species admired for its bright yellow-edged fins, vivid blue eyes, and lively swimming behavior, making it a highly attractive choice for planted and peaceful community aquariums. Although modest in size, males show impressive fin displays and active interactions within the group, creating a cheerful sense of movement and color in the aquarium. This species is generally peaceful, but its natural beauty is best expressed when kept in groups with similarly gentle tankmates and in a stable environment with clean water, moderate flow, and plenty of plant cover. By maintaining calm conditions and avoiding sudden water quality changes, aquarists can enjoy the elegant coloration, social behavior, and distinctive charm that make Pseudomugil furcatus one of the most popular blue-eye rainbowfish in the hobby.
