However, once their numbers are brought up so that there are at last five of them, most of the aggressive behavior will disappear. Any zebra danios that aren’t kept in a school, will often become stressed and may begin to display aggressive behavior towards other fish in the aquarium. Since they are a schooling fish, they need to be kept in groups of at least five, and five danios can quickly become cramped in a 10-gallon (37 litre) aquarium. While they can survive in a 10-gallon (37 litre) aquarium, they tend to only really thrive in larger aquarium. They are constantly zooming around their aquarium, and because of this, should be provided with the largest aquarium possible – or at least the largest one that you can fit into your budget. People who has ever kept zebra danios, will often swear that these fish have a touch of ADHD. They also tend to be a short-lived fish, and most will only live two to three years in a home aquarium, though it’s not unheard of for some to live as long as four or even five years. With that being said, some have been known to reach sizes of 2.5 inches (6cm) and there have been reports of even larger ones. Zebra danios stay relatively small in the home aquarium, and most will only grow to around 2 inches (5cm) in length. Because of this, they are adapted to a wide variety of water types, and if given enough time to adapt, will thrive in most home aquariums. While many of the original zebra danios in the fish trade were wild-caught, nearly all the ones available now have been breed in captivity on fish farms. But their preferred habitat is usually water with a moderate amount of current. In the wild, they can be found in everything from fast flowing streams, to stagnant rice fields. They were originally found in the streams of India, Pakistan and several bordering countries, but have since spread as an invasive species in several US states. In addition to their attractive coloring and stripes, the zebra danio has a well-founded reputation for being a playful and curious fish and makes an excellent addition to almost any community fish tank. The zebra danio (Danio rerio) is one of the most iconic fish in the aquarium hobby, and many people have owned this interesting fish at some point in their lives. Water Conditions: pH 6.5-7.2 and Soft to Medium Hard All fish are treated with Flubendazole before finally going on sale.Minimum Tank Size: 5 Gallon (10 Gallon Recommended) During this time, we treat for any health issues that may occur during transport and ensure each fish is eating well and looking healthy. Achieve a water temperature of 78F to trigger spawning and remove adults once spawning has taken place.Īll our fish are quarantined on arrival for two weeks. To breed successfully, it is advised to set up a separate aquarium with some thin-leaved plants and shallow water and larger grained gravel to allow eggs to fall between and out of the reach of their parents. They do so by scattering their fertilised eggs. They are prolific breeders, producing hundreds of eggs every other week. The Zebra Danio is often one of the first breeding projects suggested to us, and for good reason. For the best colour and health, it is advised to offer some live foods like daphnia. We recommend a mixture of quality flake food, along with high protein granules. When it comes to feeding, these little fish will eat almost anything you provide for them. Aquatic plants are advised for the best contrast between the black and white of the fish and the green or red of the plants.Īnother appealing feature of the Zebra Danio is their diet. The ideal aquarium setup would be a long aquarium to provide ample space to swim. In their natural habitat in India and Bangladesh, they can be found in a variety of environments. For these reasons, we would suggest avoiding tankmates like Guppies, Angelfish and Betta splendens. When in a group, they will swim almost constantly and while we like to think of them as peaceful fish, which they are, they can however be seen to nip the fins of tankmates from time to time. When we consider these active, slender and black and white fish, the first thing that comes to mind is their very active behaviour.
Due to the genetics of the Zebra Danio being similar to us humans, they are a very good species to study on.
Not only that zebra Danio but they have also been involved in medical studies since the 1960s. No seriously, they have been on board the international space station as part of a study. Potential Tankmates: Similar sized Gouramis, loaches, small catfish and barbs.
Minimum Aquarium Size: 50l aquarium minimum for a small group.
