The zebra danio is a freshwater fish of the danio group, in the family Cyprinidae. Zebra danios have slim bodies with horizontal black and white zebra-like stripes.

~~FAQs~~

~Can you keep just two zebra danios?~

No, you cannot keep just two zebra danios. Zebra danios are schooling fish, so they need to live in groups to feel happy and safe.

Even though keeping two is better than keeping a single zebra danio, two fish aren’t enough to form a school. With only two, your zebra danios will become stressed, lose their appetite, become anxious, contract diseases, or even display aggression towards other tank inhabitants.

You should keep at least five zebra danios together so that they can form a proper school and thrive.

You must also ensure the tank is conducive to the danios’ active nature. Each zebra danio needs at least two gallons of water to swim freely, so you’ll need a 10-gallon tank or bigger for a small school of zebra danios.

~How long can zebra danios go without food?~

Zebra danios can go up to 14 days without food. Zebra danios are very hardy and have a higher fasting tolerance compared to other species. A healthy adult danio has sufficient body mass and fat reserves to help them survive without food.

However, you shouldn’t leave your zebra danios starving for two weeks, as this can lead to malnutrition, sickness, and even death. You should feed your zebra danios once or twice a day.

Only feed them what they can finish within three minutes to avoid polluting the water. If you’re worried you might be overfeeding your zebra danios, you can let them fast for one day every week without any problems.

~How many zebra danios can I put in a 15-gallon tank?~

You can put up to eight zebra danios in a 15-gallon tank. As a general rule, one inch of fish requires one gallon of water to thrive, and a fully grown zebra danio is approximately two inches long. Therefore, each zebra danios need two gallons of water to swim freely.

You can thus fit seven or eight zebra danios in a 15-gallon tank. If you can afford to get a bigger tank, then go for it. Zebra danios are very active and love swimming around, so they’ll appreciate having more space to explore.

However, you should note that this general rule is for species tanks only. If you have a community tank, then you also need to consider the other tank inhabitants.

~Do zebra danios need an air pump?~

Yes, zebra danios need an air pump. Zebra danios are very active fish, so they benefit from the extra oxygen and movement in the water that an air pump can provide. Because of these benefits, zebra danios should have an air pump in their tanks.

Aside from an air pump, here are some other things zebra danios need in a tank:

-A heater

-A thermometer

-A water filter

-Aquarium light

-Fine gravel or sand as substrate

-A lot of live or silk plants

~Why are my zebra danios at the bottom of the tank?~

Your zebra danios are at the bottom of the tank because:

-Some zebra danios simply like the bottom of the tank

-They’re sleeping

-They’re stressed

If your zebra danios respond well to stimulation, swim actively, and have a healthy appetite, they’re likely okay even if they like staying at the bottom of the tank.

However, if they’re also behaving oddly, losing their appetite, or seem sluggish, they might be stressed. Many factors can stress out zebra danios, including poor water conditions, lack of food, poor nutrition, change of environment, incompatible tank mates, an overcrowded tank, or even loneliness.

If you notice them laying at the bottom of the tank, check their environment and living conditions immediately.
