Caring for Harlequin Rasboras

Harlequin Rasboras thrive in tanks of at least 40 liters, providing open swimming areas alongside live plants to replicate their natural habitat. They prefer water temperatures between 22°C and 27°C, with a pH range of 6.0–7.5. Subdued lighting and a dark substrate enhance their colours, while regular water changes and proper filtration ensure a healthy environment.

Feeding 

A balanced and nutrient-rich diet is essential for maintaining the vivid colouring and vitality of Harlequin Rasboras. Provide high-quality flakes or micro-pellets as their primary food, supplemented with live or frozen options like brine shrimp, daphnia, and bloodworms. Enhance their diet with AquaMunch Instant Decapsulated Brine Treat, a convenient and nutrient-dense option that supports their growth, energy, and bright colouration.

Ideal Tank Mates 

These peaceful fish thrive in community tanks with other non-aggressive species, such as tetras, Corydoras, guppies, and small gouramis. To encourage their natural schooling behaviour, keep them in groups of at least six. Avoid housing them with large or aggressive fish, as their small size makes them vulnerable to predation.
