“Angelfish aggressive behavior” is a popular phrase word in social media nowadays.
Aquarists have taken a great deal of interest in and have paid a lot of attention to angelfish, which is a very popular species of aquarium fish.
Various aquarium fish enthusiasts have found this type of aquarium fish to be an exciting one to study and keep because of the unique characteristics and features it possesses.
Honestly, you will have to get to know the angelfish very well in order to successfully keep them in your fish tank because of the unique nature of the angelfish.
Are Angelfish Aggressive?
Angelfish are known to be aggressive, don’t you think? It is true that Angelfish display aggressive tendencies among fishes, and so do other fishes.
Because they are such an active and feisty species, they tend to exhibit an aggressive nature such that they are not the best tank mates to have.
Angelfish need a lot of care, so keeping them is a challenge that needs a lot of understanding and caution.
Facts About Keeping Angelfish
This species of fish originated from the freshwater Amazon River in South America, and once they became common in home aquariums, they entered the home aquarium market as a freshwater species from the Cichlid family.
In most cases, aquarists at community aquariums or at private aquariums ask whether angelfish display natural characteristics of aggression since they have been known to show some of these characteristics naturally.
In actual fact, angelfish can be quite a lot of fun to keep, and their interesting appearance is guaranteed to liven up your aquarium.
The only problem is that because they are aggressive by nature, they might not be the easiest to keep for beginner aquarium keepers.
They also exhibit aggressive eating habits that make them a threat to other fishes, particularly small ones, because they are carnivorous.
Cobias enjoy live foods, pellets, flakes and some plants among others, which makes them can be aggressive eaters.
Despite this, they are not fussy and are not in need of a lot of attention for them to thrive. There is no doubt that angelfish make an aquarium look colourful and are a very healthy kind of fish which will thrive in almost any home aquarium if it is properly maintained.
Angelfish, when kept in favorable conditions, can grow to a length of around six inches, but they may even surpass the average length with maturity, reaching up to about ten inches long.
These fish are generally more attracted to tall aquariums rather than short and shallow ones.
This can be attributed to the fact that they have long fins that other fish sometimes bite at, which is what makes them so dangerous.
There has been evidence that these animals can live up to ten years in a healthy and comfortable environment, and if suitable conditions are available.
It is important to note that angelfish males and females very much resemble each other in appearance.
It’s unusual to see much of a difference between the size and color of male and female angelfish since the males and females are usually very similar in appearance.
Usually, you will only notice a slight difference in their papillae during the time when they are breeding. It may be difficult however for a beginner to realize this during this time.
Why Are Angelfish Usually Aggressive?
They are inherently territorial in nature, which is why they are so aggressive. By being aggressive in water, they are communicating with one another who is higher in the food chain.
Some of the reasons why this happens aren’t due to any particular issue, but due to the fact that the aquarium seeks out its best staff.
The reasons for this have been missed for years. Although there have been some observations that having too frequent water changes might upset the balance of their social ranking, they might need to re-establish themselves after every water change.
In order for the population to survive up to now, it has been necessary to remove waste excretions from the water by way of urine.
In most cases, changing the water will nullify the effects, and the tank will end up with a fresh, competitive power struggle.
If an angelfish is competing with a similarly aggressive type of fish, that could also result in excessive aggression on the part of the angelfish. It has been seen that a pair of angelfish with another pair would attempt to subdue the other competitors and not try to cooperate with the others.
Consequently, in community aquariums, angelfish are usually kept as the only dominant fish so that they do not become overpowering.
It should be noted that an inadequate diet is also one of the main reasons for angelfish aggression.
Though they do not seem to mind eating whenever they want, angelfish would not enjoy being in an environment where they have to compete with one another for food.
They would likely be aggressive towards other small fish if this occurs and may chase them and eat them.
It is also considered possible that the angelfish’s aggressive nature could be increased during their breeding season.
The aggression might be an indicator that your angelfish is about to lay her eggs if you notice an increase of aggression from what it usually is.
How To Reduce Angelfish Aggression
As a first step, you should understand what angelfish really are and the natural behaviour that they exhibit.
It should be noted that in case of excessively and uncontrollably aggressive behavior, you might be able to find some solutions for the reasons above that could reduce such undesirable behavior.
In order to maintain a calmer tank, you may want to change the water less frequently because of the stability and balance that is provided by the social ranking.
The problem with keeping a dirty tank, however, is that you will cause them further irritation and will ultimately put their health at risk.
Additionally, you should remove any breeding angelfish from your aquarium. These fish can often be aggressive towards other fish. Similarly, you should maintain water that is well-fed, healthy and suitable.
If you take the appropriate measures to take care of the angelfish and choose appropriate tank mates for them, they would be less aggressive.
Are Angelfish Hardy?
It should be noted that although angelfish have the reputation of being super unfriendly, they are not very hardy, even though they are fed very well and are not fussy at all.
The purpose of this introduction is to introduce you to some species of fish that become quite well known for their capability in flourishing in specific water conditions, as well as having pure and clean water in their aquariums.
Ensure that the filtering system in your tank is also suitable for the angelfish if you wish to ensure their survival.
Moreover, these fishes are very susceptible to some fish diseases such as Ich, which can cause you some inconveniences and problems if they are spread to other fishes in your tank.
Also, it is believed that they are not the best swimmers, so they are not likely to live in a tank with a high level of current. In addition, these fish do poorly in an overcrowded aquarium, or in water with poor sanitation.
Furthermore, many of them are not used to living in noisy surroundings and if the situation is suddenly elevated, they may even die from it. As a result, they are obviously considered to be a little bit fragile.
Are Angelfish Aggressive With Each Other?
Angelfishes tend to be kept best with a small group of their own kind, according to their keepers. Angelfish of different varieties can be kept together because there are many different breeds of angelfish as a result of crossbreeding.
You should also keep in mind that aggressive behaviors usually occur only when the living conditions are not optimal.
There are times when aggressive behavior of angelfish can be significantly reduced if there is little competition among fishes for food.
Despite the fact that you shouldn’t be afraid to house your angelfish together in one aquarium if you do so, you need to be careful.
It is important to keep in mind that there are both freshwater angelfish as well as saltwater or marine angelfish so it ought to be taken into consideration that there may be a challenge of aggression.
So, it would not be possible to keep marine angelfish in a freshwater angelfish tank because of the physiological differences.
Marine angelfish are also a very exciting fish to keep and can be kept for quite a long time.
Nevertheless, the maintenance of a saltwater aquarium may be a bit more challenging for the average person than the maintenance of a freshwater tank.
It can be seen, therefore, that freshwater angelfish have become the most common fish kept in aquariums at home.
Being a member of the Cichlid family, it is usual for them to be naturally aggressive and obnoxious fighters given that they come from the same family as this species.
Any tank containing angelfishes will have a hierarchy and the angelfishes will fight to maintain their position among the others.
Are Angelfish Aggressive Towards Other Fish?
While angelfish can be aggressive at times, they are normally able to live peacefully among other types of fish even if they are aggressive.
Even though they may not be one of the more prominent fish in a tank, they still would do what they are accustomed to because they are the dominant species.
Because these are cichlids, as well as being aggressive creatures, they may eat the baby fry in the tank given their cichlid natures.
The majority of the angelfish that was found in the aquarium paired up in pairs and chased other fishes.
Thus, it might be a good idea to keep smaller fish in the aquarium, so that the angelfishes are not eaten by them.
In order to avoid having your aquarium turned into a battleground, it would be inadvisable to keep another type of aggressive fish besides your angelfish.
Angelfish, in spite of their sheer size, can reach up to ten inches in length, so it is reasonably obvious that they would be tempted to eat any fish that would fit into their mouths.

Is it better to keep angelfish in pairs?
Angelfish do very well when they are paired up. There are a large number of angelfish that pair up with one of the same kind and go off to breed together as a group.
Moreover, if all of the angelfish were put in one tank, the pair would soon form, and the dominant pair would take over the tank, letting the rest of the angelfish feel lonely.
An angelfish, when it is still young, can be a good tank mate if kept together with other fish. The aggression of an angelfish begins only as the fish reaches maturity.
As a result of this, if you have a number of small or young angelfish, you should be able to keep them living peacefully together under the same circumstances.
How easy is it to keep angelfish?
The unique features of angelfish would make them fairly difficult for many aquarists to handle.
Beginners are likely to have a tougher time handling them. On the other hand, this isn’t completely true either. There are actually quite a few conditions required in order to maintain them if you fulfil all of the necessary ones.
Is an angelfish capable of eating other fish?
Angelfish can eat fish up to three times their own size in their tank, as long as they are smaller than themselves. There is a strong likelihood that they will experience this especially if they do not eat well or are hungry.
There is a beautiful fish called an angelfish, but it is very aggressive. The species is prone to being aggressive by nature.
As such, understanding their behaviors in this regard should be taken seriously. Having this information will allow you to gain a fair understanding of what’s going on and how to deal with it.
Providing them with the best possible care will effectively reduce their tendency to be aggressive in a reasonable amount of time.
