Do Zebra Danios Jump? Is A Cover Necessary For These Fish?

Last Updated on February 13, 2022 by cmoarz

Do zebra danios jump? It’s an important question to ask if you’ve just recently purchased some of these exquisite fish. Especially when you need to set up a tank that may require a cover.

The answer is pretty straightforward, But there are some things you are going to need to know in addition to it.

Do Zebra Danios Jump?

First, let’s get this out of the way. Do zebra danios jump? Yes, they do. These quick fish are quite capable of launching themselves out of your tank if it doesn’t have a cover on top, which could lead to their deaths.

Normally, *most* fish won’t jump out of a tank unless there is something wrong with them, the water, or the environment they are in. However, Zebra danios aren’t “most” fish.

Even when they’re maintained properly, and the zebra danios are perfectly happy in their environment, they will still try to jump out! It’s just in their nature.

Is a cover really necessary for these fish?

Some people might be wondering if they can get away without a cover over their zebra danio tank. The answer is “Not really”.

I myself have tried in the past, as have my colleagues. The end result has always been the same. Eventually, the danios will attempt to jump out of the tank.

So, it really isn’t worth the risk of having these fish if you don’t have a cover over them.

Now with that said, Not every cover will do an equal job, There are some things you need to pay attention to.

Things to consider when making or buying a cover for Zebra Danios

Zebra Danios are like little ninjas. They’re very quick and can jump quite high. So, if you buy a cover for your tank that doesn’t seal all the way or has any opening on it (even little ones), they will find their way out of your tank.

Heck, These guys are so pro at escaping, they can even climb up the output of a filter and get out the hood if it’s not completely sealed.

The important thing to look for in a cover for your zebra danio tank is that it is completely sealed. This will ensure that the only way for your zebra danios to get out of their tank is if you actually lift off the cover for them!

You might be wondering how you can get around this problem if your tank doesn’t have a hood. The answer is simple, just buy a piece of plexiglass and place it over the top of your tank.

Plexiglass is perfect for this application because it doesn’t cost all that much, and you can cut it to fit any size tank, and it will let overhead light shine through. Now you can keep those little guys in!

If your hood already has a feeding hole or any other holes in it, You should attach the plexiglass door (or another aquarium safer material) to cover the holes of your hood with aquarium-safe silicone sealant. This will prevent your zebra danios from jumping out too!
