Written by John Sawyer in Fish Species,Zebra Danios

As a zebrafish keeper, you must know about all the essential factors before adding them to your tank to ensure adequate development and a longer lifespan. So, how many zebra danios should be kept together? Let us find out.

Zebra danios are schooling species that need to get paired in at least a group of five. Placing zebra danios in an insufficient number of schools can make them suffer from extreme stress and other health issues. Consider putting zebrafish in an adequate number of schools for their longer lifespan.

The article below discusses how many zebra danios should be kept together in the tank. In addition, we will also discuss the cons of not placing your zebra danio in an adequate number of schools.

What is the ideal number of zebra danios to keep in the tank?

You should keep at least a school of five zebra danios in the tank to ensure their good health and a longer lifespan.

Not keeping your zebra danios in an adequate number of schools can lead to excessive stress in your fish, eventually making them weak and prone to several diseases.

So, we advise you always to place your zebra danios in an adequate number of schools to provide a stress-free environment and ensure your fish’s longer lifespan.

How many gallons of tank do I require for five zebra danios?

The average size of zebra danios is between 1-2 inches. So, as per the one-inch-one-gallon rule, you will require at least a 10-gallon tank to house five zebra danios.

The one-inch one-gallon rule refers to one gallon of water per inch of your zebrafish.

Avoid placing a school of five zebra danios in less than a 10-gallon tank as it will not provide enough room for your fish, eventually making them suffer stress and other health issues.

Placing your zebra danios in a small tank or a bowl can also affect the growth of your fish.

So, we advise placing a school of five zebra danios in at least a 10-gallon tank for their adequate growth and development.
