Is Danio rerio a freshwater fish?
The zebrafish (Danio rerio) is a freshwater fish belonging to the minnow family (Cyprinidae) of the order Cypriniformes. Native to South Asia, it is a popular aquarium fish, frequently sold under the trade name zebra danio (and thus often called a “tropical fish” although both tropical and subtropical).

The zebrafish – Danio rerio – is a tropical freshwater fish originally found in Eastern India’s Ganges River and native to the southeastern Himalayan region. The vertebrate takes its name from the horizontal blue stripes running the length of its body.
How were Casper fish derived?
casper was developed by selective breeding of two previously described recessive pigment mutants: 1) nacre, which harbors an inactivating mutation of the mitfa gene, rendering the fish devoid of pigmented melanocytes; and 2) roy orbison, a mutant with a so-far unidentified genetic cause that lacks reflective …
Why do scientists use zebrafish?
Because of its fully sequenced genome, easy genetic manipulation, high fecundity, external fertilization and rapid development, and nearly transparent embryo, zebrafish are a unique model animal for biomedical research, including studies of biological processes and human diseases.
Where do zebrafish originate from?
Can danios eat goldfish flakes?
Most danios are omnivorous and will thrive on Aqueon Tropical Flakes, Color Flakes, Tropical Granules and Shrimp Pellets. Frozen and live foods can also be fed as treats or to help induce spawning.
Is Danio a fish?

What is Casper zebrafish?
The Casper fish, a transparent zebra fish (Danio), was developed at the Children’s Hospital Boston for use in cancer research. Casper fish are the result of a cross between 2 mutant zebra fish, nacre and roy, that produce offspring with transparent skin and scales.
How are Casper fish different from other Casper fish?
After a year, they developed the Casper Fish™, which lacks pigment in its skin and scales, and therefore is transparent. The Casper Fish’s transparency allowed researchers to extend their research into the adult stage of this model organism.
What is unique about zebra fish?
As a vertebrate, the zebrafish has the same major organs and tissues as humans. Their muscle, blood, kidney and eyes share many features with human systems. Zebrafish have the unique ability to repair heart muscle. For example, if part of their heart is removed they can grow it back in a matter of weeks.
What does Danio rerio stand for?
“The complete sequence of the zebrafish ( Danio rerio) mitochondrial genome and evolutionary patterns in vertebrate mitochondrial DNA”. Genome Research. 11 (11): 1958–67. doi: 10.1101/gr.156801.
When was the genus Danio first described?
Danio was described in the early 19th century by Francis Hamilton. Two of the species included by him in the genus, still remain valid— D. dangila and D. rerio. About a century later (1916) and with many more species described in the meantime, the genus was split; the larger species into Danio and the smaller species into…
What is the generation time for Danio rerio?
The approximate generation time for Danio rerio is three months. A male must be present for ovulation and spawning to occur. Females are able to spawn at intervals of two to three days, laying hundreds of eggs in each clutch. Upon release, embryonic development begins; in absence of sperm, growth stops after the first few cell divisions.
What is the difference between a danio and a Devario?
The genus name Devario was suggested for the larger species with Danio being applied only to the smaller fish (with the exception of the type species, D. dangila which can grow to around 89 mm SL).
