Species group: Danios
Other common names: Zebrafish; Longfin Zebra Danio; Danio rerio
Scientific name: Danio rerio
The Zebra Danio is native to the Ganges River basin in Eastern India. They are an active and peaceful schooling fish, and are very popular amongst freshwater aquarium enthusiasts. We have a separate page for the genetically modified (GM) fluorescent Zebra Danio called the GloFish.
Zebra Danios are hardy and a good starter fish for new tanks. They are fun to watch because they are always active and when they are fed they become a blur of fish as they get worked up into a frenzy over food. Being attractive, active, fun to watch, readily available and easy to care for, they are one of the best species for beginners.
Danios are easy to feed because they love food. They will accept flakes, pellets, and frozen brine shrimp or blood worms.
The Zebra Danio has a base color of cream with bluish horizontal stripes like a zebra. They are a small torpedo shaped fish with a lobed tail.
Danios are peaceful and get along well in most community tanks. They are "frenzy" eaters and will scare shy fish away from the food. Good tank mates are Tetras, Dwarf Gouramis, and Cory cats.
Zebra Danios are tolerant of a wide range of tank parameters. They enjoy swimming around well-planted and decorated tanks, but do well even in newly established aquariums. Because they are hyperactive and tend to escape by jumping, aquariums must have a good-fitting cover. They need a minimum of a 10 gallon tank.

blue-stripped fish the kids will love
Zebra fish are a great little fish for the home aquarium. They prefer company so be sure to get a large enough tank to hold several of them. As long as you keep the tank clean and at the right temperature, they should be happy little fish in community. Paired with some guppies or other colorful fish and you can have a nice little tank at home. Be careful pairing with longer-finned fish as there's always a risk for fin-nipping. Their adult size is ~3-4 inches long, although if they are kept in a crowded tank they will not get that big. They do well on flaked food as well as brine shrimp. Overall Zebra fish are a solid choice for an at home tank. .

Looks bad, but fish recover
Stress brings on this viral disease. The fish will recover if most cases. But if you have a dead fish, for any reason, remove it immediately. If fish eat a dead fish, the virus may be transmitted. The rotting fish will cause a stressful spike in ammonia and nitrite. Remove dead fish right away!!!.
