The Zebra Danio is a well-known aquarium fish and has been a popular choice for many years. As an aquarium fish the Zebra Danio is very hardy, adaptable and well suited to most water conditions and aquarium environments. The fish are active and should be kept in groups, timid fish may find their constant activity a little overwhelming. The fish can be kept in heated or unheated aquariums. A long finned variety and a spotted 'Leopard Danio', a colour morph of the Zebra Danio are also available. The leopard Danio Danio frankei has rather unknown origins and no-one is certain whether it is a cross breed, selective bred variation, or even a naturally occurring species. Both zebra and leopard danios are excellent aquarium fish and well recommended for beginners.
In recent years the Zebra Danio has been genetically modified by introducing jellyfish genes, amongst others, to exhibit a glowing red colour. If you see these fish for sale we recommend you find out about the ethical concerns of such fish before you decide to purchase or avoid these fish.
