"Giant danio The giant danio (""Devario aequipinnatus"") is a tropical fish belonging to the minnow family Cyprinidae. Originating in Sri Lanka, Nepal, and the west coast of India, this species grows to a maximum length of 4 inches (10 cm), making it one of the largest of the danionins. It is characterized by a blue and yellow, torpedo-shaped body with gray and clear fins. In the wild, giant danios live in clear streams and rivers among hills at elevations up to 1000 ft (300 m) above sea level. Their native substrate is small gravel. They are native to a tropical"
"Danionin The danionins are a group of small minnow-type fish belonging to the family Cyprinidae. Members of this group are mostly in the genera ""Danio"", ""Devario"" and ""Rasbora"". They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. ""Danio"" species tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels.

The grouping of fish now deemed danionins has been the subject of constant research and speculation throughout the 20th century. Nearly all the fish classed within the genera ""Danio"" and ""Devario"" were originally placed in the genus ""Danio"" upon discovery. However, in the first part of the 20th century, George S. Myers split them into three genera, ""Danio"", ""Brachydanio"", and ""Daniops"". The sole species within Myers' ""Daniops"", ""D. myersi"", has long ago been found to be a synonym of ""Devario laoensis"", but"

The only ""Danio"" species to have been consistently called ""Danio"" were ""D. dangila"" and ""D. feegradei"". As ""D. dangila"" was the first discovered ""Danio"" (or type) the name ""Danio"" had to remain with ""D. dangila"", which is why the vast majority of species were moved to ""Devario"".

Its use as a laboratory animal was pioneered by the American molecular biologist George Streisinger and his colleagues at the University of Oregon in the 1970s and 1980s; Streisinger's zebrafish clones were among the earliest successful vertebrate clones created.

As surface dwellers, their diets consist predominantly of exogenous insects, but is also supplemented by worms and crustaceans. In captivity, giant danios will usually accept most foods. They are a somewhat aggressive fish, and may bully other fish in community tanks. Giant danios appreciate water movement to simulate the motion of the rivers and fast-moving streams of their origins, and prefer to school.

""Microrasbora"" was not considered to be a part of the danionins, nor even closely related to ""Danionella"", a part of the danionins as understood at that time. In the late 1980s and 1990s, doubts grew about the validity of ""Brachydanio"", with species being referred to their original naming of ""Danio"", and Fang Fang determined that the genus ""Danio"", recognized up to that point, was paraphyletic. Fang restricted ""Danio"" to the species in the """"D. dangila"" species group"", which at the time comprised nine species including ""D. dangila"", ""D."

However, ""Danio dangila"" and ""Danio feegradei"", both of which had most of the characteristics of the ""Brachydanio"" (with the exception that they were much larger than ""Brachydanio"" species) were placed within ""Danios"".
