Males are easily distinguished from females by their brighter colours and longer and more elongated dorsal fin and therefor cost more.
Pseudomugil furcatus is a small species growing to a length of about 5 or 6 cm. They have two dorsal fins, separated by a small gap, the first much smaller than the second. The body colour is yellow-green in both males and females.
Best kept in a densely-planted aquarium and an excellent choice for the carefully-aquascaped set-up.
The addition of some floating plants and driftwood roots or branches to diffuse the light entering the aquarium also seems to be appreciated and adds a more natural feel.
The water should be well-oxygenated and a degree of flow is advisable.
Do not add this fish to a biologically immature aquarium as it can be susceptible to swings in water chemistry.
Water conditions reported from their natural habitats are: Temperature 24-28.5°C; pH 7.0-8.0 and Hardness 90-180 ppm.
