Oscar is a kind of fish famous for its notorious, aggressive traits. It is a plain deceiver through an oscar fish is hard to imagine about its beautiful attitude to swim. Yet the oscar fish proves that the look can be deceiving to its enemy.
Those who are brave enough to put these on my initially be attracted by their looks and colors, but their intelligence and social behaviors quickly come to be appreciated.
These are the kind of animals that only experienced fish keepers should look after. As a universal, they are easy to feed, but difficult to find suitable tank companions.
Oscar fish is definitely a suitable species for any place in your home; Their complex behaviors will captivate you for hours.
Oscar (Astronautus ocellatus) is a species of Cichlid, so it should not be surprising that they come from the Cichlid family. Most of the cichlids come from Africa or South America, this being the latter.
They are native to Brazil, Colombia, Ecuador, French Guiana, and Peru. They are found along the Amazon River and its surrounding regions, which is one of the world’s most bio-diverse environments.
Wild populations have been found elsewhere (in places like North America and China), although they are only spread in the region through the fisheries industry. These fish are very popular for home aquariums, but they will not be bought without thinking. They are notorious for aggressive and regional behavior that can make them difficult to manage.
It is a species full of personality. A few different varieties have been developed that provide different colors and patterns. Choose wisely because they can live 20 years if they are in good health.
You will find Oscar fish at most aquarium stores – a healthy person can be found for under $ 10.
The Oscars are regional, so adding them to your tank can be risky.
They are not afraid to attack other fish and if a fish enters their territory they will do so. Timing of feeding and feeding can increase their aggression.
Most of their time will be spent swimming in the middle level of the tank, though they often leave the level in search of food. You will see their trees uprooted and decorated during this search, so everything in the aquarium should be protected.
The good news is that if the tank is set up correctly and you choose the right tank companion, their aggression can be controlled.
Most varieties grow up to 12 inches in reach. They reach this size pretty quickly in their lifetime, growing one inch a month until fully grown.
They have long oval bodies. The dorsal and anal fins extend throughout the body into the soft feathers, creating a fan behind. As this species is monomorphic you will have difficulty in having sexual intercourse, which means both sexes look similar. Look closely at it for genital separation.
Classically these cichlids consist of irregular black and orange colored splits (Tiger Oscars), but colors may change over time.
Many varieties have been created through selective breeding.
The bodies of red and lemon oscar fish are almost completely red or yellow bodies, respectively, their wings are black or white.
Albinos are another popular choice. You can find albino varieties for many species, people are attracted to dark white which covers the whole body.
What does the Perfect Oscar Tank do?
Remember, fish have evolved to live in their natural areas, so you need to set up your aquarium to replicate these natural conditions.
The new aquarium of South America is warmer with a neutral pH, so Oscar cannot handle acidity or alkaline extremes.
Water flows become stronger as most populations are found in rivers like the Amazon. When the sun’s light is strong, the water will not be crystal clear so the intensity of the light is lost as the water is exposed to water.
At the bottom of the river there will be a soft layer on which rocks, debris and vegetation are scattered.
Rebuilding these conditions in your tank is fairly easy.
At the base of the tank, there should be a layer of soft layers. The softest layers are fine-grained, so the sand would be ideal. The Oscars prefer to dig so that a thick layer scratches them.
The most natural look is to place rocks and bogwood around the tank, but you are free to choose any decoration. Make a few caves for each fish so they have somewhere to hide in their area. Also, remember to firmly fix the décor in place.
These species will dig around objects while looking for foods that can remove them.
Live plants are unlikely to be eaten, but they are still not safe. Like décor, trees can be uprooted when they dig up the layer.
Use tough plants so they can avoid trauma. Floating plants should be safe from damage, a good alternative is Horn-wort.
Ideal water conditions are between 74-81 ° F, pH 6-8, and 5-20 KH.
You don’t need any special equipment to keep the water healthy, just a filter to clean it and a heater to maintain an ideal temperature range. Most aquarium lights are also suitable.
Attach the equipment to the tank tightly or they will enjoy the hands (or fins) of the Oscars. টি Keep the lid on because these fish can be strong and jump or force other fish to jump.
While they prefer strong currents in the wild, a strong enough current should be created at the filter outlet, so you won’t need any water/air pumps.
What size of Oscar does Aquarium need?
The Oscars will require a fairly large aquarium, ideal for 55 gallons or larger. A small tank will cause them stress which will make them sicker or more aggressive.
How many gallons can be stored per?
Their size and area needs mean that each fish needs plenty of space. Try 55 gallons for the first Oscar, then another 20-30 gallons for each additional fish.
Oscar Tank Mates
This breed is not the best at making friends. Due to their aggressive nature, tank mates can live in fear (assuming they haven’t already eaten).
In South America they live in several different regions of the world, so they are accustomed to lots of other fish.
However, this is not the same in a tank because there are so few places, so the tension rises. If you want these cichlids, only a tank at the Oscars is probably the best idea.
If you want to transform your tank into a community, you need to pick a few large, passive fish to be able to defend yourself.
Some good examples include: Aruanus, Bichirs, Convict Cichlids, Firemouth Cichlids, Green Terriers, Jack Dempsey, Jaguar Cichlids, Selphin Plecos, Severum Cichlids and Silver Dollar. As you can see, companion Cichlids are the most common tank mates since they can usually hold their own against the Oscars.
Any small fish you add will quickly disappear from the tank. This will be the same for small violators like shrimp and snails.
The Oscars put together
Oscars can be put together and this is usually the safest option. Just make sure to follow the socks guidelines mentioned above
Due to their need for territories they can attack tank companions. Make sure their territories have plenty of space as it minimizes territory disputes.
What to eat at Oscar Fish
Finding the right tank mates for the Oscars can be difficult, but not providing healthy food. They are public and you can eat anything you give them
In the wild they used to eat small fish, larvae and small pieces of tree debris. Small insects and crustaceans make up the largest portion of their diet.
The easiest option in the aquarium is to use store-bought flake / pellet foods. They are designed to contain all the nutrients your fish needs, you can even buy something special for cichlids.
Other options include straight / frozen foods (which are full of protein). These include blood worms, sea shrimp and daphnia. Live food encourages Oscars to catch their food that reveals their natural prey tendency.
If you have some extra greens around your kitchen, you can cut them off and put them in the tank. Or you can use them to make homemade fish dishes.
Although they may be small in plants, it will not be a big part of their diet if you feed them enough food.
The best diet will be a mixture of different food types so your fish will have healthy nutrients
Feed them a few times a day, to the extent that they can finish completely in minutes. Keep an eye out for aggression as these cichlids become excited around food.
How to Care for Oscar Fish
Oscars require more care than other species.
Their size and big appetite mean that they produce a lot of mess.
This makes it very important to clean the tank or the condition will deteriorate rapidly. Ideally perform water changes at least twice a week.
These cichlids are stronger than most fish, so they are often not ill, but they can be just as sick as all species.
One of the common problems with these fish is “head lice” disease. This is where cavities and holes begin to form.
This can be a sign that they are not getting enough nutrition in their diet. If you see signs of this disease, it is worthwhile to change their diet.
These are one of the hardest fish for captive breeding.
Individuals are very picky when it comes to picking mates, so you can’t assume that putting an older man and wife together will make a teenager.
You can try to buy an already established breeding pair. Another option is to buy a group of teenagers, as they grow up together, they will make connections and are more likely to create a mate.
One of the problems with the second option is that it will take a while to breed as the apples grow until your teens are mature.
One problem with the second option is that it will take some time to breed as you have to wait until your teens are mature; It takes 1-2 years.
Unless Oscar thinks they have found the right partner, you can adjust any number of people of different castes.
Naturally, these fish will breed “during the rainy season”. Try lowering the temperature to a few degrees to give a rainy signal to the aquarium. Water changes every few days, in addition to splashing water on the surface for several minutes each day.
When the fish are ready to make a spawn they will ignite their gill and use their wings to persuade their mate. It can be simple fin waggling or shaking.
For laying eggs, the pair will clean a rock surface. The largest female can produce up to 3,000 translucent white eggs.
Both parents will protect the eggs until they hatch (after 2-5 days); While wives fan them to keep the substrate from hating it, men keep other fish away.
Take teens into a new tank with a sponge filter for the best chance of survival. Feed them about 2-4 times a day to help them grow faster. As they grow larger, they will need to be removed again or the tank will become too small and their growth will stop.

Distribution and Accommodation
A. Ocellatus is native to Peru, Ecuador, Colombia, Brazil, and French Guiana and occurs in the Amazon River Basin, the Amazon, Io, Negro, Solimis, and Ukayali rivers, and in the Apragus and Wapak rivers.
In natural environments, the species is commonly found in slow-moving white-water habitats and has been found to shelter under submerged branches.
As a by-product of the deciduous fish trade, mountain populations also occur in China, North Australia, and Florida in the United States of America.
The species is limited in its distribution by the intolerance of cold water temperature, the lower lethal limit for the species is 12.9 ° C (55.22 ° F).
Although the species is widely regarded as sexually monomorphic, males are advised to grow faster, and some naturally occurring males are thought to have dark spots at the base of their dorsal fins.
The species reaches sexual maturity by the age of one year,  and has been reproducing for 9-10 years.
The frequency and time of spank may be related to the occurrence of rainfall. A. Ocellatus fishes are sporadic at two big-mountain levels, although detailed information on their reproduction in the wild is scarce.
In the woods. Most of the fish that eat ocellatus are comparatively fasting catfish, including species of Buenocephalus, Rinelloricaria, and Ochmecanthus.
The species uses a suction process to catch prey, and Parachromis friedrichstali and Nimbochromis livingstonei have been reported to display mimic “dead bodies” in a similar fashion.
The species also has a final requirement for vitamin C and in its absence develops health problems. Captive Oscars usually eat fish foods designed for large carnivorous fish: crayfish, worms, and insects (such as flies, crickets, and tuna).
