The Zebra Danio is a common freshwater fish that many people keep as a pet. 

It is known for being very social as well as easy to take care of. Its vibrant colors and peaceful nature make it an excellent addition to just about any tank.

Zebra Danio Appearance

Zebra Danios grow up to around two inches long, so you can keep quite a few of them without having to get a huge tank. The silver and gold color scheme of this fish is enhanced by its five blue horizontal stripes. These royal blue stripes extend from near the eye to its caudal fin.

Females are usually a bit larger with a rounder body than the males. These fish come in a wide range of colors, including the albino variety. This gives you plenty of options to choose from. While an albino Danio makes for a great pet, it doesn’t survive very long in the wild. One of the best defense mechanisms these fish have is their dark overall coloration.

Natural Habitat

You will be able to find the Zebra Danio through Eastern India. They tend to occupy slow-moving bodies of water, such as stagnant ponds.

1. Tank Setup

If you are going to care for a Zebra Danio, it is important that you focus on creating the best possible habitat. This means getting a tank that is at least 10 gallons. While you might be able to get away with a 5-gallon tank, this is not recommended.

You don’t need a powerful, high-end filter for this type of tank setup. These fish naturally prefer slow-moving water, which is why you don’t want to use a filter that will create a strong water flow. A standard hang-on-the-back filter will do just fine.

Fine sediment makes for an excellent substrate for these fish. Just make sure that you wash this material before putting it in the aquarium. The material should be soft so that it doesn’t injure your fish at all. You’ll also want to throw in some caves and plants so these fish have a place to take shelter. You can also use large round pebbles, as this simulates the fish’s natural environment.

Amazon Sword Plants and java fern are two good vegetation options to consider with this sort of tank setup. These plants will oxygenize the water while making your aquarium look nice as a whole.

2. Water Conditions

You should make sure that the water has a pH of 6.5 to 7.2, and a temperature that ranges from 64 to 77 degrees Fahrenheit. A heater isn’t really a necessity, but you can definitely use one.

3. Zebra Danio Tank mates

Some of the different fish species that Zebra Danios peacefully co-exist within the wild include Emerald Pufferfish, Scarlet Badis, and the Honey Gourami. They get along well with a variety of species, so you shouldn’t have much of a problem finding tank mates.

You might want to consider putting in some African Dwarf Frogs or even Blue Velvet Shrimp. guppies and Mollies do not make good tank mates for these fish, as they will most likely fight. You also want to avoid putting in any fish that are known for their predatory instincts, such as Tiger Barbs or Betta Fish.

4. Zebra Danio Food

The Zebra Danio is an omnivore, which means that you can give it lots of different foods. This includes everything from worms to larvae. Look for high-quality fish flakes, as they will satisfy most of this fish’s nutritional needs.

You can sometimes give this fish certain vegetables, including peas, cucumber and even zucchini. They also like small crustaceans, which can make for an excellent treat once in a while. It is important that you only give these fish as much food as they can eat within three minutes. Overfeeding your fish can lead to all sorts of health problems.

Common Health Problems

Zebra Danios are prone to disease and illness when they are kept in cold water, which is why it is so important to regulate the temperature. They can develop dropsy, which is a fairly common disease that fish get in captivity. It can be very serious, especially if they don’t receive treatment right away. Bacterial infections are always a concern as well. If you start to notice any lethargy or unusual behavior with your fish, you should take notice.

Zebra Danio Breeding

If you want to breed Zebra Danios, you will have to keep the males and females in their own breeding tanks for at least three weeks. Make sure that you keep the temperature of the water in this tank at 71 to 80 degrees Fahrenheit at all times.

While you have the fish separated, you’ll need to give each of them Bloodworms, daphnia, and other live foods they eat in their natural habitat.
