Buying Oscars for your fish tank has the potential to be so much fun. It’s good for you to learn more about these fish before buying them, though.
Do you want to keep Oscars in a community fish tank? You can do this, but you need to make sure you pick appropriate tank mates.
What tank mates are the best options for Oscar fish? Will Oscar fish make good community tank members or are they better kept alone?
Read on to learn more about Oscar fish tank mates. It’ll give you the information that you need to make good choices for your community aquarium.
Can Oscar Fish Live with Other Fish?
Yes, Oscars can be kept in community fish tanks with other fish. However, you can’t put them in a tank with just any other fish.
If you put these fish in a community tank without researching compatibility, things aren’t going to go well. Simply put, some of the fish could get hurt and you could even be placing your Oscars in danger.
No matter what type of fish you own, it’s important to look into compatibility when setting up a community fish tank. Fish will only be compatible with certain other types of fish.
You want to ensure that every fish you put in the community aquarium is compatible. Each type of fish needs to be compatible with the Oscars as well as the other fish that you put in the tank.
That means that there will be a lot to learn before moving forward. If you rush things and don’t do the necessary research, you could easily wind up losing fish.
Thankfully, there are many great options when looking into Oscar fish tank mates. Later, you’ll learn about many of the best fish to put with Oscars in community aquariums.
Do Oscars Eat Other Fish?
Oscars will indeed eat other fish from time to time. This isn’t unusual, though.
You see, Oscars are omnivorous fish that are going to take the opportunity to eat when they can. They will eat smaller fish that will fit in their mouths.
This isn’t something that is unique about Oscars that makes them dangerous. Oscars just do the same things that other omnivorous fish do to eat.
If you put small fish in the tank with Oscars, the Oscars are going to eat them. You can’t put fish in a community tank with Oscars if they’re small enough to get eaten.
In captivity, Oscars commonly grow to be between ten and twelve inches long. They’re rather large fish, and that means that they can eat many popular types of aquarium fish that are a bit too small.
Oscar Fish Eating Goldfish
Goldfish will not be safe when kept in fish tanks with Oscars. Oscar fish are far larger than goldfish and will likely be able to fit the goldfish in their mouths.
Any small fish that can fit in an Oscar’s mouth will be devoured. Thus, it’d be a poor idea to put Oscars with goldfish in a community tank.
It’s also not a good idea to feed goldfish to Oscars on purpose. This shouldn’t become a normal part of the Oscar’s diet.
Goldfish can be enjoyable fish to care for, but they should be kept separate from the Oscars. Give them their own tank and keep Oscars in a larger community tank with appropriate tank mates.
Oscar Fish Eating Guppies
Guppies are far too small to be put in a fish tank with Oscar fish. These fish would become a snack for the Oscars rather quickly.
As mentioned above, fish that are too small will get eaten by Oscars. Guppies easily fit into the Oscar’s mouths.
You can’t blame the Oscar fish for being omnivores. This is why you need to research things ahead of time so you can avoid making mistakes.
Don’t put any guppies in the fish tank with Oscars. These smaller types of fish need to be kept in fish tanks with other small fish that they’re compatible with.
Can Oscar Fish Live with African Cichlids?
No, African cichlids won’t be a good fit for your community tank if you’re caring for Oscars. Oscars and African cichlids have far different care requirements overall.
Also, many types of cichlids are known to have problems getting along. There’s a good chance that the two types of cichlids would fight each other in a community aquarium.
You don’t want to have to deal with problems such as this. It’s simply not a good idea to put African cichlids in the same tank as Oscar fish.
Oscars have many better options when you’re looking for community tank members. You can find tank mates that are truly compatible with them.
Can Oscars Live with Parrot Fish?
Some people have been able to keep Oscars and parrot fish together. However, you could encounter problems with aggression if you aren’t careful.
These two fish might come into conflict if the fish tank isn’t big enough. If you wish to keep Oscars and parrot fish in the same tank, it’s imperative to buy a large aquarium.
You want to give the Oscars and the parrot fish more than enough space. It’ll keep them separated and make it more likely that they can coexist in the tank.
It’s often wise to put hiding spots in the tank, too. Decorations such as caves and rocks can help to give the fish hiding spots so they won’t have to fight.
Even knowing this, it might be best not to put parrot fish in the tank with Oscars. They aren’t the most compatible fish even if some enthusiasts have managed to make it work.
Can Oscars Live with Angelfish?
It’s a terrible idea to keep angelfish in a community aquarium with Oscars. Many types of angelfish are a lot smaller than Oscars.
Even if they aren’t small enough to get eaten by the Oscars, they could wind up getting hurt. The Oscars might wind up bullying the angelfish.
Both angelfish and Oscars are territorial and they could easily come into conflict. It’s very likely that the angelfish will get killed by the Oscars in the tank.
There are some claims that certain aquarium experts have been able to keep angelfish and Oscars in the same tank. However, it’s not usually going to go well at all.
If you’re a beginner or someone with moderate experience, it’s a poor choice to keep these fish together. Generally, it’s not recommended to put angelfish in a community tank with Oscars.
Can Oscars Live with Silver Dollar Fish?
Silver dollar fish are some of the best tank mates for Oscars. These are very peaceful fish that are going to leave the Oscars alone.
They’re large enough that Oscars aren’t going to be able to eat them. These fish grow to be around six inches long on average.
Since the silver dollar fish will be large enough to avoid being seen as prey, the Oscars will leave them alone. They won’t bother them and you can enjoy having both of these fish in your tank.

So long as the Oscars and the black ghost knife fish have enough space in the tank, this will be a good experience. It’s worth noting that black ghost knife fish are nocturnal fish.
You’ll love how interesting these fish are to look at. They’re pretty and they’re also quite shy most of the time.
Can Oscars Live with Reedfish?

Oscars are commonly kept with red-tailed sharks as tank mates. It’s recommended to place caves in the tank for these fish so they can hide when they feel the need to.
Red-tailed sharks also like aquatic plants if you can find options that the Oscars won’t ruin. You’ll likely see the red-tailed sharks living near the bottom of the fish tank.
Can Oscars Live with Convict Cichlids?
Convict cichlids are interesting fish because they have an almost zebra-like appearance. Indeed, sometimes these fish will be sold as zebra cichlids.
They’re also called convict cichlids because their stripes resemble the stripes on old-fashioned prisoner outfits. It’s easy to see that they’re beautiful fish that will stand out in a fish tank.
Are they any good as tank mates for Oscars, though? They can work out well as tank mates for Oscars.

Sometimes they might come into conflict with the Oscars. However, they’ll only defend their own territory and the fights shouldn’t get too bad.
Thus, they aren’t perfect tank mates for the Oscar fish. They’re decent tank mates for Oscar fish that can work out okay if you give the fish enough space.
Can Oscars Live with Firemouth Cichlids?
Firemouth cichlids are also known to be compatible with Oscar fish. This is partially because firemouth cichlids are closely related to the convict cichlids mentioned above.
You’ll find that firemouth cichlids aren’t too aggressive overall. Even so, they grow large enough that they won’t be bothered by Oscar fish in a community tank.
These fish are good at swimming around and staying away from fights, too. They’ll get away from the Oscars if the Oscars ever do become aggressive in the tank.

Oscars can pick on these fish a bit, but it usually isn’t a big deal. If the fish tank is more than big enough, it’s likely that the Oscars will leave them alone.

Will Oscars Eat Snails?
Perhaps you’re considering putting snails in the community fish tank. Sometimes people keep snails in tanks as cleaners.

Pick good fish for the tanks such as plecos, silver dollar fish, and clown loaches. Some types of cichlids such as convict cichlids can work out okay as tank mates, too.
You want to avoid incompatible tank mates such as angelfish. The Oscars could wind up hurting the angelfish if you put them in the community tank together.

Now that you know all of this, you can set up an ideal community aquarium. It’ll look great and you won’t have to worry about your Oscars bullying other fish or being bullied by more aggressive fish.
