The Purple Harlequin Rasbora is a vibrant color variation of the classic harlequin rasbora, prized for its soft purple sheen and signature black triangular “harlequin” marking. Peaceful, hardy, and highly social, these schooling fish are perfect for planted aquariums and community tanks. Their synchronized swimming behavior and shimmering coloration create a beautiful, calming display that stands out in natural aquascapes.
Approximate Shipping Size: 0.75–1 inch
Appearance
Purple Harlequin Rasboras feature a warm copper to lavender-purple body tone accented by a bold black wedge marking along the rear half of the body. Under proper lighting and stable water conditions, subtle purple iridescence becomes more visible, especially when kept in groups. Their streamlined shape and constant movement make them visually appealing midwater swimmers.
Temperament & Behavior
These rasboras are extremely peaceful and thrive in groups of 6–10 or more. Schooling behavior becomes more natural and visually impressive in larger numbers. They are active but gentle fish that coexist easily with other small community species.
Care Requirements
Purple Harlequin Rasboras prefer stable aquariums with gentle filtration, live plants, and shaded areas. A planted aquascape with open swimming space helps reduce stress and encourages natural schooling behavior.
Tank Size: 15 gallons minimum
Temperature: 74–80°F
pH: 6.0–7.5

Aquascape: Live plants, driftwood, open swimming areas, subdued lighting
Tank Mates
Excellent tank mates include small tetras, Corydoras, dwarf shrimp, ricefish, peaceful gouramis, small rainbowfish, and other gentle community species. Avoid aggressive or large predatory fish.
Diet & Feeding
Purple Harlequin Rasboras are omnivores that readily accept high-quality micro pellets, flakes, and frozen foods. Supplement with baby brine shrimp, daphnia, and finely chopped frozen foods to promote strong coloration and healthy growth.
