Guapote Jaguar Cichlid (Parachromis managuensis): Aquarium Care Guide

Jaguar cichlids (also known as Managuense) are a popular freshwater species that many aquarists are familiar with. However, many of them are intimidated by this fighting fish!

While there are definitely a few things to know if you plan to keep this fish in a home aquarium, we feel that the lack of information on this species is not helping.

That’s why we put together this guide. You’ll learn everything you need to know about caring for jaguar cichlids, plus general information about the species that will make you a more prepared owner.

Species Summary

The jaguar cichlid is one of the most popular species in the cichlid family. With their distinctive appearance and fierce personality, these fish are a must-have for any hobbyist looking for a challenge.

These fish have many different names. In addition to being called Jaguar Cichlids, you may see them labeled Managuense Cichlids or Aztec Cichlids. When found in their natural habitat, locals often refer to them as Guapote Tigre.

Originally, the fish come from Central America. They can be found in freshwater bodies in Honduras and Costa Rica. Scientifically, they are 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, they can reach massive sizes and require a pristine environment to stay healthy.

Life expectancy

The average lifespan of a jaguar cichlid is about 15 years!This means that if you’re thinking of getting one for yourself, be prepared for a bit of a compromise.

However, that is just a rough average. Some owners have been able to extend the life of their fish beyond 15 years with attentive 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 appearance. These are large fish with a distinctive profile made for hunting.

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

While many cichlids tend to have short, stubby fins, that is not the case with the jaguar cichlid. The dorsal and caudal fins are quite prominent. Thanks to the thorns, they take on a somewhat menacing look. The anal fin is also very prominent, especially in males.

There are some notable differences between the male and female specimens. One of the easiest ways to tell them apart is by looking at their fins. Males have extended dorsal and anal fins that stretch to a pleasing point. In general, males are also noticeably larger than females.

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 will notice that the lower jaw extends slightly beyond the upper jaw. You might even be able to see some of the predator’s sharp teeth. This unique look isn’t just for looks. It also helps in hunting.

You see, their jaws can protrude up to 90 percent of the length of their mouth ! It is certainly a sight to behold during mealtime!

When it comes to coloration and pattern, Jaguar Cichlids are very unique. One of the coolest things about this fish is that it changes in appearance as it ages.

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

As your fish ages, those black bands will slowly turn into spots! This is what gives the fish that iconic jaguar color pattern. Thats not all. Once the black bands have disappeared, larger black spots will appear.

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

Jaguar Cichlid Size

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

Females are usually 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 over 3 pounds!

Author’s 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 good, you can expect your fish to hit the higher end of the size spectrum. It might even top the 16-inch mark.

Jaguar Cichlid Care

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

That said, these fish are not the most difficult to care for from a maintenance and habitat standpoint. They are quite hardy and adapt well to a variety of water conditions. As long as you check the water quality regularly and provide a comfortable environment, you should have no problems. Here are some important things to know about Jaguar Cichlid care.

tank size

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

In general, juvenile fish can do well in a small 30-gallon tank. However, they will quickly get over that.If you plan to keep a single adult Jaguar Cichlid, you will need a tank size of 70 gallons minimum.

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

Here is our personal recommendation:

In our opinion, the ideal Jaguar Cichlid tank size is in the 100 to 125 gallon range.That should provide enough space for a single jaguar cichlid to roam freely and be healthy.

If you want to keep a breeding pair (more information at the end of the guide), you should increase the tank size to at least 180 gallons. Even close couples can show some signs of aggression from time to time. A massive tank ensures that both fish can have their own space.

water parameters

When creating the perfect environment for jaguar cichlids, it is 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. The water is usually very warm and relatively neutral.

The best thing about jaguar cichlids is that they are very tolerant. Unlike other fish that cannot handle even the slightest change in parameters, cichlids do well. In fact, these fish are capable of surviving temperatures of up to 97 degrees!

However, it is always best to stay within a small range and avoid large fluctuations if possible. Try to keep temperatures relatively moderate, as warmer waters tend to provoke 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 your tank

Establishing the perfect environment for jaguar cichlids is not too difficult. The lakes, ponds, and rivers that these fish occupy in the wild are often cloudy and littered 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 sand substrate. Sand is better for jaguar cichlids. Sometimes they like to dig and the sand will allow them to do so safely.

Avoid gravel and rough rocks that might fit in your mouth. The last thing you want is to deal with digestive problems 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 potted. Jaguar Cichlids love to uproot plants and cause destruction in your tank. So make sure everything is safe and secure.

Rocks, caves, and driftwood are great too. They can provide some good hiding places. Consider adding a flat rock or a large cave system in case your fish spawn.

Try to keep most of the decorations around the perimeter of the tank. Some pieces towards the center are fine.

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

In terms of equipment, a powerful filtration system is essential. Large sump-style filters or a cartridge filter like the Fluval FX will work to handle all the waste your fish produce.

Always choose a system that is efficient for your tank size. This fish can quickly build up ammonia and nitrate levels, so your gear needs to be equipped to handle all of that.

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

Diseases to be aware of

Despite their hardiness, jaguar cichlids are not immune to health problems. Fortunately, you don’t have to worry about any problems specific to this species. They are hardy fish that will stay healthy with the right water conditions.

The only thing you will have to worry about are the common diseases that affect all freshwater fish. This includes Ich and infections.

Ich is a particularly unpleasant problem that is often caused by stress. It can result in white spots all over the body of the fish. If not taken care of, it can lead to death. In addition, it is highly contagious.

The best way to avoid Ich is to stay aware of water conditions. Take measurements regularly and make any necessary adjustments. Also, be sure to do regular water changes to prevent ammonia and nitrate buildup.

Author’s Note: Always be careful 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 their closed ecosystem from becoming a breeding ground for disease.

Food and diet recommendations

Providing these fish with a healthy diet is paramount. High-quality food not only keeps them healthy, but 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 on a protein-based diet.

It can provide feeding fish, insects, crickets, worms, and just about anything else you can fit in your mouth. These fish are opportunistic eaters and will readily consume anything provided to them. This includes dry or frozen foods.

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

Temperament and general behavior

As we have mentioned before, jaguar cichlids are very aggressive fish. They will fight any fish in the tank and try to eat smaller creatures. This includes smaller fish and invertebrates. As a result, they are not large community fish.

They are very territorial and will not tolerate any other fish entering their space. Many fish will pick a fight and go to great lengths to kill other fish that come across them.

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

When it comes to their general behavior, you will often see your Jaguar Cichlid swimming around the bottom half of the tank. They might go down to the substrate to dig a bit before investigating another area of ​​the tank. They are quite active!

Jaguar Cichlid Tank Mates

Finding good Jaguar Cichlid tankmates comes down to understanding their temperament and natural compatibility.

The best fish you can have with a jaguar cichlid is another jaguar cichlid. United couples can do well and live a happy life together. The easiest way to do this is to buy a pair that has already been put together. Or, it may group together several juvenile males and females for a short period until those bonds are formed.

Author’s Note: Juvenile jaguar cichlids are not as aggressive as adults.

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

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

  • oscar fish
  • green terror cichlid
  • convict cichlid
  • red devil cichlid
  • flowerhorn cichlid

Again, it’s important to note that these tankmates may work for some people and fail for you. With aggressive fish, it is your responsibility to identify the individual temperament of each specimen and separate those that are too aggressive to live together.


Breeding jaguar cichlids is not difficult. Because they pair naturally, half the work is already done. To make things even easier, these fish make excellent parents.

They are very protective of the eggs and fry. The females will even exhibit maternal behaviors as the little fry grow.

If your bonded mate is in a shared tank with other fish, keep an eye on their behavior. When it’s time to breed, they usually start to be 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 playback process with a few simple steps. Raise the temperature a few degrees and do 50 percent water changes a couple of times a week. Provide enough high-quality live food and your fish will be ready to breed in no time.

The females will swell with eggs. She will then find a flat rock or cave to place them. Female jaguar cichlids can lay more than 2,000 orange eggs at a time. At this point, the male will fertilize the eggs.

The eggs take 5 to 7 days to hatch. During this time, the female will remain close by and the males will guard the entire area. For this reason, you should keep the pair together away from other fish. The male will fight to the death to protect the eggs.

After hatching, the parents can dig a hole in the sand and transfer the little fry to keep a closer eye on them. Baby fish will not swim freely until they are about a week old. At that time, you can provide 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 open to owning one.

If you still consider yourself a beginner, it’s probably a good idea to skip for now. There are many other fantastic freshwater species that require much less work.

But if you have a little more experience and are up for the challenge, we encourage you to give it a try! We have always said that having a fish that requires a higher level of care is not only more rewarding, but the best way to improve your skills as a hobbyist.
