Characteristics

They are native to the fresh water rivers and streams of southeast Asia, but many species are brightly coloured, and are available as aquarium fish worldwide. A number of the species have only been recently discovered, in remote inland areas of Myanmar and do not yet have scientific names.


They have two pairs of long barbels and are generally characterised by horizontal stripes (with the exception of the Glowlight Danio, Panther Danio and Black Barred Danio which have vertical bars). They range from 4 cm/ 1.75 in) to 15 cm/ 6 in) in length. They generally do not live for more than two to three years and are probably annual fish in the wild. This koi carp has two pairs of barbels, the second pair being quite small. ... Binomial name Danio choprai ({{{author}}}, {{{date}}}) Glowlight danio, Danio choprai: Maximum length: 1. ...

Aquarium Care

The care of members of the genus Danio are rather similar and easily generalized. They are easy to moderate in difficulty to keep.


All of these fish are primarily surface feeders. They are omnivorous in the aquarium and will accept a wide variety of foods, though flake food is appropriate. Living in aquaria, live/frozen flaked foods are suitable, especially brine shrimp and sinking tablets. When conditioning Danios for breeding, it's advisable to feed them plenty of fresh foods. It has been suggested that Sea-Monkey be merged into this article or section. ...


Although boisterous and liable to chase each other and other fish, they are good community fish and will not generally attack each other or other fish, although they occasionally nip fins, more by accident than design and will, like most fish, eat eggs and any fish small enough to fit into their mouths.


They are best kept in a tank long enough for their active swimming, preferably with a current from a power filter (or at least airstone) as they often live in fast flowing streams in the wild. Generally this also results in them being sub tropical with cooler temperatures. They are good jumpers and a tight fitting lid is recommended


Schooling fish, they prefer to be in groups of six or more. Danios prefer water with a 6.0–8.0 pH, a water hardness of up to 5.0–19.0 dGH,a carbon hardness of 8 to 12 KH, and a temperature range of 68–80 °F (18–24 °C), the lower end of the temperature range is ideal. The correct title of this article is . ... The title given to this article is incorrect due to technical limitations. ... Fahrenheit is a temperature scale named after the German physicist Daniel Gabriel Fahrenheit (1686–1736), who proposed it in 1724. ... Celsius is, or relates to, the Celsius temperature scale (previously known as the centigrade scale). ...


Breeding

Some species of Danios, such as the Zebra Danio are among the easiest aquarium fish to breed. Other species such as Danio kyathit are far harder to spawn. All scatter their eggs over the substrate. The eggs are non adhesive and hatch within 2-3 days. Eggs will be eaten enthusiastically unless protected by a layer of marbles or heavy substrate planting. Binomial name Danio rerio (Hamilton-Buchanan, 1822) The Zebra Danio or Zebrafish (Brachydanio rerio or Danio rerio) is a tropical fish, commonly kept in aquaria and used for scientific research, belonging to the minnow family (Cyprinidae). ...

Clades

There are four clades or subgroups within the Danio Genus: A clade is a term belonging to the discipline of cladistics. ...

It is possible that the Danio dangila clade may be separated into a separate genus from the others, owing to their larger size etc., however other than larger size and larger egg size they are very similar to the other danios in anatomy and behaviour so this is unlikely at the present time. If they were split off they would retain the title "Danio" with the other danios renamed, because the "type" of Danio (first discovered Danio)is Danio dangila, which is within this clade.
