It’s great to own Oscar fish so long as you have enough room for a big tank. There are pretty big fish that require big fish tanks to be happy in a home aquarium.
Sometimes you might encounter issues with Oscar fish jumping, though. If an Oscar fish tries to jump out of the tank, is this an indication that something is wrong with the environment?
Read on to learn about Oscar fish and why they might try to jump out of a fish tank. You’ll learn what’s likely going on so you can make changes.
It’s Normal for Oscars to Jump in the Wild
One thing to know right away is that jumping is a natural behavior for Oscars. These fish like to jump and it’s something you’ll see them doing in the wild.
They might jump for many different reasons in the wild. In a fish tank, there are usually only a few reasons for jumping.
Jumping might not be anything to worry about. However, it can also be problematic.
Below, you’ll learn more about Oscar fish and why they might choose to jump in a fish tank. Depending on your situation, you might want to make some changes to keep the fish safe.
1 – Oscars Jump When They See Food
Perhaps the most common reason why Oscars jump is because they see food. When an Oscar fish sees something that it wants to eat, it might jump in response.
It could be jumping out of excitement or it might jump in an effort to eat the food before another fish can get to it. If you’re seeing Oscars jump during feeding sessions, this isn’t going to be anything to worry about.
If your Oscar sees something at the surface of the water that it wants to eat it might jump. Sometimes this can be an issue because you don’t want your Oscar fish to jump out of the tank and die.
You’ll learn the simple solution to this problem later on. There are also other reasons why Oscars jump that you should consider.
2 – Poor Water Conditions
When the water conditions in the fish tank are bad, it’ll be tough for the fish to live normally. Poor water quality will stress the fish and it’ll potentially make them sick.
Have you been doing regular water changes? Oscars are messy fish that can make the fish tank dirty faster than you’d think.
You need to have a powerful filter to help keep the water clean. Even with a good filter, you must do regular water changes.
It’s also important to monitor the water parameters to keep things where they need to be. When things get out of hand, it’ll cause the ammonia levels in the tank to spike.
This makes it incredibly difficult for the Oscar fish to breathe. It might try to jump out of the water simply because it can’t breathe well.
3 – Bullying Issues
Bullying in the fish tank could be to blame for the fish jumping as well. Oscar fish can be put in community fish tanks, but you need to approach things carefully.
Oscars are fairly aggressive fish, but they’re calmer than many other large cichlids. You could easily put Oscars in a fish tank with fish that aren’t compatible with them.
If you don’t do the necessary research, you might make mistakes when putting together a community aquarium. This could lead to the Oscars becoming severely stressed due to bullying.
When Oscars get bullied by larger or more aggressive fish, it might make it hard for them to keep going. The fish might choose to attempt to jump out of the tank to reach safer waters.
The fish don’t know or understand that there isn’t water on the outside of the fish tank. They jump because they think that it’s better than staying in the tank due to the danger presented by the bully fish.
Never put your fish in such a bad position. You want them to thrive under your care.
It’s fine to put Oscar fish in a community fish tank. You just have to pick tank mates that will be compatible enough with them.
There are all sorts of good options to consider. Many types of catfish are known to get along well with Oscars.
You also need to make sure not to overcrowd the fish tank. Overcrowded fish tanks will stress the fish just about as much as bullying issues.
Be careful and only put as many fish in the tank as you can comfortably fit. You want the Oscars to have more than enough room to thrive.
Put a Lid On the Fish Tank
Putting a lid on the fish tank is the best way to solve this issue. It’ll make it a lot easier for you to keep the fish from jumping out.
Of course, you want to solve issues in the tank that might make the fish want to jump. You should be monitoring the water parameters to keep things where they need to be.
It’s also imperative to keep the water in the tank clean. Otherwise, the poor Oscar fish will suffer in the aquarium.
Bullying issues need to be addressed immediately, too. The bully fish could kill your Oscars if you don’t take action.
Typically, Oscars won’t try to jump out of the tank for no reason. If the Oscar is trying to jump out of the water, it’s likely you need to take note of certain problems and solve them.
Putting a lid on the tank is mostly useful for when you don’t want the fish to jump out due to seeing food. An Oscar could accidentally hurt or kill itself by jumping out of the tank.
A lid makes it impossible for the fish to jump out. So long as the lid is secure, it’s not going to be able to bump the lid off when it attempts to jump.
You’ve now learned about Oscars and why they might choose to jump out of the tank. It could be due to stress, poor water quality, or even bullying.
Sometimes these fish jump when they see something they want to eat, too. It’s wise to put a lid on the tank to get the fish from being able to jump out.
You don’t want the fish to get killed or injured due to jumping. Just be sure to solve issues with stress in the tank as well.
