Belonging to the minnow family Cyprinidae Giant Danios are well, the largest danios in the danionins neighborhood. Reaching to a maximum length of 4 inches (10 cm). They can be found in clear streams and rivers among hills at elevations up to 1000 ft (300 m) above sea level. Originating from Sri Lanka, Nepal, and the west coast of India, Danios have become quite popular among aquarist, due in part of their ability to adapt to a broad scope of different water conditions, ranging from cold-water to tropical aquarium communities.
A very active fish, they enjoy been in schools of six or more. Excellent swimmers, it is best to keep them in a 50 gallon aquarium where they can be mixed with american cichlids like the angels. Small tanks are not recommended, since they will not offer the require space for them to swim. A solitary giant danio in a small/medium tank will soon become boisterous and nippy towards his/her tankmates.
Danios in general prefer the water to be slightly acid. Regular partial water changes are important. Cover the tank, as they are excellent jumpers.
Breeding them is not difficult, but identifying the sexes can be tricky since there are not particular distinctions between males and females.
