Danio rerio commonly known as the Zebrafish is a tropical fish belonging to the minnow family (Cyprinidae), commonly kept in aquaria and used for scientific research. Zebra Danios are of no economic importance in commercial fisheries as a food fish, but very commonly known and popular in the aquarium trade.

Are zebrafish poisonous?
The distinctive saltwater zebra fishes (Pterois), used in marine aquariums, have extremely large pectoral fins, numerous extremely poisonous spines, and colourful vertical stripes.
What is zebra fish good for?
Zebrafish have all the main organs involved in the process of metabolism and can be used to study several human metabolic disorders such as nonalcoholic fatty liver disease, type 2 diabetes mellitus, dyslipidemia, and other hepatic diseases.
What is zebra fish eat?
General observations and gut content analyses indicated that zebrafish consume a wide variety of animal and plant matter, including zooplankton and insects, phytoplankton, filamentous algae and vascular plant material, spores and invertebrate eggs, fish scales, arachnids, detritus, sand, and mud.
How are zebrafish like humans?
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.
Why are zebrafish commonly used to test new human drugs?
As a toxicology model, zebrafish has the potential to reveal the pathways of developmental toxicity due to their similarity with those of mammals. Zebrafish therefore, provides a sound basis for the risk assessment of drug administration in humans.
How much DNA we have in common with chimps and zebrafish?
According to one source, we share about 98 per cent of our DNA with chimpanzees, 85 per cent with the zebrafish and 36 per cent with a fruit fly.
What type of fish is a Danio?
Danio is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia, commonly kept in aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbels.
How big do Tiger Barbs get?
Reaching an adult size of 2 1/2 to 3 inches, they are large enough to avoid being eaten by large fish, yet small enough to keep a school of them in a modest-sized tank. For a striking display, set up a species-specific tank with a half dozen of each color variation of tiger barb, complemented by live plants.
Can zebrafish be aggressive?
Despite the fact that zebrafish is a gregarious species that forms shoals, when allowed to interact in pairs, both males and females express aggressive behavior and establish dominance hierarchies.
Can zebrafish live with goldfish?
Zebrafish are peaceful, tiny fish that like to swim in groups. They may start out at about one inch in length and max out close to two inches, making them significantly smaller than most types of goldfish. Due to their different body size, they can be combined with both comet and fancy varieties of goldfish.
Can zebrafish help your eyesight?
The tiny zebrafish may hold the key to slowing or even reversing eye diseases that affect millions of people, especially our aging population. The reason for this is that zebrafish, unlike mammals, are able to regenerate an injured or diseased retina.
Why zebrafish are better than mice?
While mice are evolutionarily more similar to humans because they are mammals, zebrafish have several advantages over their furry competitors. One important advantage of zebrafish is that the adults are small and prefer to be housed in large groups, or “shoals”. ... Working with mice in this way is much more complicated.
How much DNA do humans share with zebrafish?
Humans and zebrafish share 70 percent of the same genes and 84 percent of human genes known to be associated with human disease have a counterpart in zebrafish.
