Roseline Shark

A streamlined schooling cyprinid with a vivid red stripe and contrasting markings. Despite its common name, this is a freshwater fish, not a true shark; adults reach about 15 cm.

Aquarium and care

Keep a group of at least six in a large, long aquarium with open swimming space. Well-oxygenated water, good filtration, and moderate temperatures around 22–25°C suit this active fish. Avoid cramped or overly warm setups.

Feeding

Offer quality small pellets or flakes, appropriate frozen foods, and some vegetable-based foods. Feed across the school so every fish has access.

Temperament and tank mates

Choose peaceful, active companions that share its space and temperature needs. Tiny timid fish and crowded displays are poor matches.
