Overview

The Greenface Sandsifter (Lethrinops furcifer) is a striking cichlid species native to Lake Malawi in Africa. Known for its peaceful demeanor towards its own species and beautiful coloration, this cichlid is a favorite among aquarists looking to add a unique sand-sifting fish to their tanks. However, their territorial nature toward other species requires thoughtful tank planning.

Origin and Natural Habitat

This species is native to Lake Malawi in Africa, where it inhabits sandy substrates and shallow waters. They are known for their sand-sifting behavior, which they use to find food in their natural habitat.

Appearance and Size

Greenface Sandsifters have a vibrant greenish-blue face and a streamlined body. Their fins may display subtle iridescence under the right lighting conditions. In aquariums, they typically grow to about 16-19 cm (6.3-7.48 inches).

Tank Requirements

• Tank Size: A minimum of 200 liters (50 gallons) is recommended to provide ample space for their territorial behavior.
• Water Parameters:
• pH: 7.5 - 8.5
• Water Hardness: 10 - 18°N (178 - 321 ppm)
• Temperature: 23 - 27°C (73.4 - 80.6°F)
• Tank Setup: Include sandy substrates for their natural sifting behavior, along with plenty of rocks and caves to create hiding spots. Ensure open swimming areas while maintaining stable water conditions.

Temperament and Tank Mates

Greenface Sandsifters are peaceful towards their own species but can be territorial and aggressive towards other fish, especially during breeding. Suitable tank mates include other peaceful Malawi cichlids like Aulonocara (Peacock cichlids) and non-aggressive catfish species. Avoid housing them with more aggressive cichlids such as Mbuna species, which can dominate and stress the Greenface Sandsifters.

Feeding and Diet

Avoid feeding high-protein, meaty foods as they can lead to digestive issues. Instead, offer a balanced diet consisting of:

• High-quality flake or pellet foods formulated for cichlids
• Occasional treats like brine shrimp and mysis shrimp
• Be cautious not to overfeed, as they can be prone to obesity

Sexing

There are no distinct physical differences between males and females, making sexing challenging without observing breeding behavior.

Breeding

Breeding Greenface Sandsifters can be rewarding with the right setup:

• Provide plenty of hiding spots using rocks and caves.
• Introduce one male with several females to encourage breeding.
• Males will dig pits in the substrate, and females will lay eggs at the edge of these pits.
• Because female sand dwellers are delicate, it may be beneficial to remove the male during the mouthbrooding period to reduce stress.
• When the fry are released, feed them newly hatched brine shrimp or finely crushed flake food.

Lifespan

With proper care, Greenface Sandsifters can live up to 15 years in a well-maintained aquarium, offering long-term enjoyment for dedicated aquarists.

Conclusion

The Greenface Sandsifter (Lethrinops furcifer) is a peaceful and fascinating species ideal for cichlid enthusiasts. Their sand-sifting behavior, vibrant coloration, and unique breeding habits make them a standout in any aquarium. With the right environment, diet, and tank mates, these cichlids will thrive and add beauty and intrigue to your tank.
