Jaguar Cichlid (Managuense): Care, Size, Tank Mates…

Jaguar Cichlids (aka Managuense) are a popular freshwater species that many aquarists know about. However, a lot of them are intimidated by this feisty fish!

While there are definitely some things you need to know if you plan on keeping this fish in a home aquarium, we believe that the lack of information about this species isn’t helping.

That’s why we put together this guide. You’ll learn everything you need to know about Jaguar Cichlid care, plus general species info that will make you a more prepared owner.

Species Summary

The Jaguar Cichlid is one of the most popular species belonging to the Cichlid family. Thanks to its distinct looks and fierce personality, these fish are a must-have for any aquarist looking for a challenge.

These fish go by many different names. In addition to being called the Jaguar Cichlid, you might see them labeled as Managuense Cichlids or Aztec Cichlids. When they’re found in their natural habitat, locals often refer to them as Guapote Tigre.

Originally, the fish hail from Central America. They can be found throughout freshwater bodies of water in Honduras and Costa Rica. Scientifically, they’re known as Parachromis managuensis and are aptly named after Lake Managua in Nicaragua, where they were originally found.

Like many other Cichlid species, Jaguar Cichlids are not for the faint of heart. Not only are they prone to aggression, but they can reach massive sizes and require a pristine environment to stay healthy.


The average lifespan of a Jaguar Cichlid is around 15 years! This means if you’re thinking about getting one for yourself, be prepared for a bit of commitment.

However, that’s only a rough average. Some owners have been able to extend the life of their fish past the 15-year mark with vigilant care and optimal tank conditions. This will take a lot of work and consistency, but it’s the approach we think all owners should take.


The most captivating part of the Jaguar Cichlid is its looks. These are large fish with a distinct profile made for hunting.

They have an elongated body that takes on an oval-like shape. Spiny rays extend from their bodies to support the fins.

While many Cichlids tend to have short and stubby fins, that’s not the case with the Jaguar Cichlid. The dorsal and tail fins are quite prominent. Thanks to the spines, they take on a somewhat menacing look. The anal fin is very prominent as well, especially in males.

There are some notable differences between male and female specimens. One of the easiest ways to tell the two apart is by taking a look at the fins. Males have extended dorsal and anal fins that stretch to a nice point. Generally, males are noticeably larger than females as well.

Another prominent feature of this fish is its head and mouth. Managuense Cichlids are fierce predators that have no problem hunting down elusive creatures in the wild. One thing that makes them so successful is their mouth.

When you look at a fish, you’ll notice that the lower jaw extends beyond the upper jaw a bit. You might even be able to see some of the predator’s sharp teeth. This unique appearance isn’t just for looks. It helps on the hunt, too.

You see, their jaws can protrude as much as 90 percent of their mouth’s length! It’s certainly a sight to behold during feeding time!

When it comes to coloration and pattern, Jaguar Cichlids are very unique. One of the coolest aspects of this fish is that they change appearances as they age.

As juveniles, these fish take on a pale goldish-silver hue. Large black bands wrap around the back of the fish and stop somewhere around the lateral line.

As your fish gets older, those black bands will slowly turn into dots! This is what gives the fish that iconic jaguar color pattern. That’s not all. Once the black bands have disappeared, larger splotches of black will appear.

Sometimes, these black patches will look like large jaguar spots. Other times, they merge together. Either way, the larger black spots almost always form a horizontal stripe that runs from the tail to the head.

Jaguar Cichlid Size

Cichlids are notorious for getting very large, and this species is no exception. The average Jaguar Cichlid size is around 14-16 inches in length when in captivity.

Typically, females are a couple of inches shorter than males. Both males and females have a fairly average growth rate.

In the wild, these fish can reach lengths of 2 feet. They can also tip the scales at more than 3 pounds!

Author Note: Several factors will affect their final size when fully grown. If you have a larger tank and do a good job of keeping the water quality in good shape, you can expect your fish to reach the upper end of the size spectrum. You might even be able to surpass the 16-inch mark.

Jaguar Cichlid Care

Jaguar Cichlids care is typically recommended for aquarists who have a bit of experience. Due to their large size and aggressive behavior, they can be a bit of a handful to deal with if you don’t know what you’re doing.

With that said, these fish aren’t the hardest to care for from a maintenance and habitat standpoint. They are pretty hardy and adapt well to a range of water conditions. As long as you check the water quality regularly and provide a comfortable environment, you should have no issues. Here are some important things to know about Jaguar Cichlid care.

Tank Size

The ideal Jaguar Cichlid tank size depends on their age and size. Since this fish can get over 16 inches in length, it’s important to make sure they have the space they need.

Generally, juvenile fish can do just fine in a small 30-gallon tank. However, they will quickly outgrow that. If you plan on keeping a single adult Jaguar Cichlid, you will need a tank size of 70 gallons at the very minimum.

70 gallons is still a relatively conservative guideline. Many aquarists have seen success with a modest tank of this size. However, if you’re trying to give your fish the most comfortable life possible, more space is always better.

Here’s our personal recommendation:

In our opinion, the ideal Jaguar Cichlid tank size is somewhere in the 100 to 125 gallon range. That should provide plenty of room for a single Jaguar Cichlid to roam free and be healthy.

If you want to keep a breeding pair (more on that at the end of the guide), you need to bump up that aquarium size to at least 180 gallons. Even bonded pairs can exhibit some signs of aggression every once in a while. A massive tank ensures that both fish can have their own space.

Water Parameters

When you’re creating the perfect environment for Jaguar Cichlids, it’s important to replicate their natural habitat as closely as possible. This is especially important when it comes to water conditions.

These fish come from a variety of lakes and rivers in Central America. Typically, the water is very warm and relatively neutral.

The great thing about Jaguar Cichlids is that they’re very tolerant. Unlike other fish that can’t handle even the smallest change in parameters, Cichlids do just fine. In fact, these fish are capable of surviving in temperatures as high as 97 degrees!

However, it’s always best to stick within a small range and avoid large fluctuations if possible. Try to keep temperatures relatively moderate, as warmer waters tend to bring out the aggressive behavior in these fish.

Here are some of the most important parameters to consider:

  • Water temperature: 73°F to 82°F (75 to 77 is the sweet spot)
  • pH levels: 7.0 to 8.7 (around 7.7 is ideal)
  • Water hardness: 10 to 15 dGH

What To Include In Their Tank

Setting up the perfect environment for Jaguar Cichlids isn’t too difficult. The lakes, ponds, and rivers that these fish occupy in the wild are usually murky and filled with plant debris. While you shouldn’t fill the tank with decaying vegetation, you can get a similar feel to keep your fish happy.

Starting at the bottom of the tank, add a thick layer of a sand substrate. Sand is best for Jaguar Cichlids. They sometimes like to dig and the sand will allow them to do that safely.

Avoid gravel and rough rocks that they can fit into their mouth. The last thing you want to deal with digestive issues or injuries because your fish decided to swallow a piece of rock!

You can then decorate the tank with some plants, rocks, and driftwood. For vegetation, stick to floating aquarium plants, or root plants that are heavily protected with pots. Jaguar Cichlids love to uproot plants and cause destruction in your tank. So, make sure everything is secured and safe.

Rocks, caves, and pieces of driftwood are great, too. They can provide some nice hiding spots. Consider adding a flat rock or large cave system just in case your fish breed.

Try to keep most of the decorations around the perimeter of the tank. A few pieces toward the center are fine.

The most important thing to remember is to avoid overcrowding the habitat. Managuense Cichlids are big swimmers and need some open space to thrive.

As for equipment, a powerful filtration system is paramount. Large sump-style filters or a canister filter like the Fluval FX4 will work to handle all of the waste your fish produce.

Always choose a system that’s efficient for the size of your tank. This fish can quickly increase ammonia and nitrate levels, so your equipment needs to be equipped to handle all of that.

Lastly, a strong pump is ideal for Jaguar Cichlid tanks. The pump will replicate the fast water flow of its natural habitat.

Diseases To Watch Out For

Despite their resilience, Jaguar Cichlids are not immune to health problems. Luckily, you don’t have to worry about any issues that are specific to this species. They are tough fish that will stay healthy with the right water conditions.

The only things you’re going to need to worry about are common diseases that plague all freshwater fish. This includes Ich and infections.

Ich is a particularly nasty problem that’s often caused by stress. It can result in white dots all over the fish’s body. If not taken care of, it can lead to death. Plus, it’s highly contagious.

The best way to avoid Ich is to stay on top of water conditions. Take measurements regularly and make adjustments as needed. Also, make sure to do water changes on a regular basis to avoid a buildup of ammonia and nitrates.

Author Note: Always be cautious when adding anything new to your tank. This can lead to a variety of infections ranging from parasites to fungi. If you notice anything strange, quarantine your fish to prevent your closed ecosystem from becoming a breeding ground for disease.

Food & Diet Recommendations

Providing these fish with a healthy diet is paramount. Not only does high-quality food keep them healthy, but it can also prevent aggression.

Jaguar Cichlids are highly carnivorous fish. They can be trained to eat flakes and pellets from a very young age, but they do best with a protein-based diet.

You can provide feeder fish, insects, crickets, worms, and pretty much anything else that they can fit into their mouth. These fish are opportunistic eaters and will readily consume anything to provide. This includes dry or frozen food.

Stick to a daily feeding schedule to keep your fish healthy.

Temperament & General Behavior

As we have mentioned earlier, Jaguar Cichlids are very aggressive fish. They will pick fights with any fish in the tank and try to eat smaller critters. This includes smaller fish and invertebrae. As a result, they aren’t great community fish.

They are highly territorial and will not tolerate any other fish getting in their space. Many fish will pick fights and do all they can to kill other fish that cross them.

Aggressive behavior is to be expected. It’s just a part of owning a Cichlid! However, you can do your part to minimize the behavior as much as possible by staying on top of water conditions and providing a healthy diet.

When it comes to their general behavior, you’ll often see your Jaguar Cichlid swimming around the bottom half of the aquarium. They might pop down to the substrate to dig around for a bit before investigating another area of the tank. They’re quite active!

Jaguar Cichlid Tank Mates

Finding good Jaguar Cichlid tank mates all comes down to understanding their temperament and natural compatibility.

The best fish you can keep with a Jaguar Cichlid is another Jaguar Cichlid. Bonded pairs can do just fine and live happy lives together. The easiest way to do this is by purchasing a pair that has already bonded. Or, you can group multiple juvenile males and females for a short period until those bonds form.

Author Note: Juvenile Jaguar Cichlids aren’t nearly as aggressive as the adults.

It is possible to keep other fish in the same tank. But, you need to be extra cautious. Avoid adding any fish that’s smaller than the Managuense Cichlid. Otherwise, it will be food in no time.

When it comes to other species, some great Jaguar Cichlid tank mates are other large Cichlids and large catfish. Here are just a few species that some aquarists have seen success with:

Again, it’s important to point out that these tank mates might work for some people and fail for you. With aggressive fish, it’s your responsibility to identify the individual temperament of each specimen and separate any that are too feisty to live together.


Breeding Jaguar Cichlids is not difficult. Because they naturally pair off, half the work is already done. To make things even easier, these fish make very great parents.

They’re highly protective of eggs and fry. Females will even exhibit maternal behaviors as the tiny fry grow up.

If your bonded pair are in a tank shared with other fish, keep an eye on their behavior. When it’s time to breed, they’ll usually start being more aggressive than normal. This is a good time to transfer them to a very large tank all to themselves.

You can also trigger the breeding process with a few simple steps. Raise the temperature a few degrees and perform 50 percent water changes a couple of times a week. Provide plenty of high-quality live food and your fish will be ready to breed in no time.

Females will swell up with eggs. Then, she’ll find a flat rock or cave to lay them. Female Jaguar Cichlids can lay upwards of 2,000 orange eggs at once. At this point, the male will fertilize the eggs.

It takes 5 to 7 days for the eggs to hatch. During this time, the female will stay close by and the males will protect the entire area. For this reason, you need to keep the bonded pair separate from other fish. The male will fight to the death to protect the eggs.

After hatching, the parents may dig a pit in the sand and transfer the tiny fry to watch over them more closely. The baby fish will not swim freely until they’re about a week old. At that point, you can provide baby brine shrimp for food.

Now It’s Time To Think

Now that you know more about Jaguar Cichlids and how to care for them, you’ll need to decide if you’re willing to own one yourself.

If you still consider yourself a beginner, then it’s probably a good idea to pass for now. There are plenty of other fantastic freshwater species that are a lot less work.

But if you’re a bit more experienced and are up to the challenge, we encourage you to give it a shot! We’ve always said that owning a fish that requires a higher level of care is not only more rewarding, but the best way to improve your skills as an aquarist.
