If you try isolating them because of their nipping problems, they will become stressed out and vulnerable to diseases to the point of death. This nipping behavior can harm other species, and cause fights and a lot of bloodsheds. If you keep them with larger breeds, they will try to bite their fins. Their relationship with large fish is peculiar indeed. It advises keeping around six or more Zebra danios in your tank. It attributes to not having a large enough tank or not having enough schooling fish in your tank.
Behavior & TemperamentĪlthough they are peaceful and keep to themselves, they do have some behavioral issues such as fin nipping. Like most freshwater species, these are small and only reach about 2.5 inches, with females reaching a maximum size of about 3 inches. These species do not survive for long in the wild because of predators. They come in all kinds of colors, including purple, blue, green, and orange. Some scientists experiment with genetic modification using jellyfish genes to create Zebra Danios that glow in the dark, known as Glofish. They have undergone so much interbreeding that their blue stripes have entirely vanished, leaving a golden-hued body with white-silvery lines all over. You can also find the golden-colored Zebra danio. In the wild, these stand out and don’t survive very long because they quickly become prey. You won’t easily find them in the wild, but they can be found quite easily in the fishkeeping industry. One scarce species is the Albino Zebra Danio. Males and females have two pairs of barbels and the same number of stripes. One popular variation of this species is the Longfin Zebra Danio, which was bred to develop longer fins than usual. They are a sexually dimorphic species where the males are slimmer, more colorful, and brighter than their silvery-white appearance.įemales also tend to be rounder and fuller-bodied than their male counterparts, who are slimmer with torpedo-like bodies. If you take a closer look, you’ll notice five blue stripes extending from the caudal fin to the head. Some breeds have sprinkling black spots on their body and almost look like leopards. These schooling fish don’t grow bigger than 2 or 3 inches and, therefore, don’t require spacious tanks. They feature horizontal blue, black, or purple stripes, easy to spot in a tank. Zebra Danios are easy to recognize because of their unique appearance. They belong to the Cyprinidae family and have interesting properties, making them popular test subjects for research and science.ĭid you know they can repair their own heart? Appearance
That’s why you can find them in just about any pet store for under $3 per fish. Originating from the rivers of India and Nepal, Zebrafish (scientific name: Danio Rerio) are popular for several reasons. Conclusion Species Overview Level of Care Very easy Temperament Extremely peaceful Appearance Natural black and white striped body with certain variations Life Expectancy Can live for over 5 years Size Reach a size of 2.5 inches or more Diet Omnivorous species Family Cyprinidae Tank Size Minimum 10 gallons of water Tank Environment Plenty of plants with freshwater Tank Mates Extremely peaceful species that thrive in community aquariums.
