❤️ Care

The Masked Julie is a vibrant and socially inclined species that requires a certain level of care to thrive in captivity. Below are details on how to best care for this beautiful aquatic entity.

Care Process

The Masked Julie is a moderately hardy species that can adapt to a range of water conditions provided previous healthy maintenance routines. It typically prefers a pH range between 6.5 and 7.8, with temperatures kept consistently between 24°C and 28°C. Being a moderate maintenance species, it is important to maintain these parameters to ensure their well-being.

Masked Julies are social creatures needing a bit of room to move, requiring about 10 liters of water per individual. They are ideal for community tanks with other social species, but during breeding, you should be mindful of their increased territorial behavior. Its natural inclination is to inhabit various levels of the tank—surface, mid, and bottom—so a well-structured environment that allows exploration and movement would be ideal.

Feeding

The Masked Julie requires a varied diet to maintain its vibrant coloration and health. They can be fed a mixture of flakes, pellets, and freeze-dried foods supplemented with live or frozen foods such as bloodworms, brine shrimp, tubifex worms, and daphnia. Vegetable matter, algae wafers, and specialized color-enhancing food can also be included to provide nutritional balance and maintain vibrancy.

Tank Setup

To mimic their natural habitat, consider having a well-decorated tank with multiple hiding spots, as Masked Julies feel more secure with adequate coverage. Rocks, plants, and driftwood can provide both shelter and territories. Ensure the tank is spacious enough to accommodate their slightly territorial nature, especially during breeding, minimizing stress and aggression.

The tank's substrate should allow for substrate spawning during breeding periods. Providing flat surfaces, such as stones or ceramic tiles, where they can lay eggs is also beneficial during this time. Their territorial behavior can become highly aggressive when breeding, so it's advisable to isolate a breeding pair or reduce the number of tank mates to minimize conflicts.

Additional Considerations

Although generally peaceful, ensuring the Masked Julie coexists compatibly with other non-aggressive species will reduce stress and conflict. Regular monitoring of water quality and consistency in feeding schedules will contribute significantly to their health and longevity. Lastly, while their popularity is high among aquarists for their coloration and social nature, breeding in captivity remains a moderate challenge, requiring attention to detail and a patient approach.
