Active Schooling Fish

Zebra Danios are highly social fish and should be kept with others of their own kind. A group of at least six or more is recommended where aquarium space allows.

Keeping them in a suitable group encourages more natural behaviour and creates an attractive, constantly moving display.

Because Zebra Danios are fast and energetic swimmers, provide plenty of open swimming space alongside plants, rocks or driftwood.

Zebra Danio Tank Mates

Zebra Danios are generally well suited to peaceful freshwater community aquariums with fish that enjoy similar water conditions.

Suitable tank mates may include:

• Other peaceful danios
• Rasboras
• Many peaceful tetras
• Corydoras
• Small peaceful catfish
• Other similarly sized community fish

Avoid keeping them with large predatory fish or highly aggressive species.

Feeding Zebra Danios

Zebra Danios are easy to feed and readily accept a wide range of aquarium foods.

A quality tropical flake or small pellet can form the basis of their diet. This can be supplemented with appropriately sized frozen or live foods such as brine shrimp and daphnia.

A varied diet helps maintain good condition, colour and activity.

Aquarium Setup

Zebra Danios appreciate an aquarium with plenty of swimming room. Plants and decorations can be positioned around the sides and rear of the tank while leaving open space through the centre.

A secure aquarium lid is recommended because danios are quick swimmers and can jump when startled.
