Do you want to know if clownfish are aggressive? From my experience, they do get angry, but if they’re getting this angry at the other clown, you might need to separate them.
My clown, “Esau,” is a little devil. Whenever I put my hand in the tank, that thing tries to bite me. He’s not mean to his partner or other fish, though.
So, however, you may be tempted to add clownfish to your saltwater coral reef tank if you want to make one.
Yes, these fish do look lovely. Also, it is the same fish as Nemo from the well-known kids’ movies. So, do they get along with other people?
So, do clownfish fight with other fish? Unfortunately, clownfish are mean to other fish, even though the Finding Nemo pictures make them look nice. Read on to find out more.
Let’s get started.

Are clownfish aggressive fish
Yes, regrettably, clownfish are often rather aggressive fish.
These vibrant little swimmers know how to splash in the aquatic world. These fish are raised in the wild on coral reefs, dangerous places for the timid.
Clownfish are renowned for being fierce fighters, which may surprise you.
Maybe it’s because their name is so scary. Clowns do, after all, have a talent for making people jump! But have no fear, dear lovers of the ocean—the reality is very different from what seems.
Clownfish are infamous for acting aggressively. They could be more aggressive and better for novices, which makes them challenging for aquarium owners and fish keepers.
In the environment, these fish are raised in competitive coral reefs where they always need to be on the lookout for predators hunting for a colorful meal.
Clownfish are fierce and territorial in large part because they are constantly fighting for their lives.
Clownfish don’t look or act like this; this is a fictional character created for them in the Pixar film Finding Nemo.
Are clownfish harmful
They are not dangerous to humans and do not have any defense mechanisms against people. However, avoiding handling clownfish or moving their tank around excessively is essential, as this can stress the fish and lead to health problems.
It is also necessary to wash your hands thoroughly before and after handling the fish or their tank to reduce the risk of transferring harmful bacteria.
Many people who consider eating clownfish wonder if they are poisonous, but the clownfish are not. However, their skin contains toxins that help the fish keep its predators at bay.
While the concentration of the toxin is not considered harmful, the fish may inflict severe intoxication if consumed in large amounts.
It would be wise to politely turn down when you are offered clownfish and need more confidence in the cooking or freshness of the fish.
Which clownfish are the least aggressive
Common or False Ocellaris Clownfish: Ocellaris Clownfish are pretty docile, unlike other clownfish species, which makes them excellent tankmates.
The fact that Ocellaris clowns are a less aggressive species is one of the reasons for their fame.
My 100-gallon tank has a pair of clownfish who appear quite pleased when other fish approach them, so I’m used to them.
Things may be different when they believe they must protect their area from other fish. Furthermore, each fish has a unique personality.
Although some reefers have observed more collectible species hostile against humans, not commonly toward fish, the Ocellaris Clownfish is generally regarded as the least aggressive species.
Clown behavior often involves the female partner “beating up” the male to demonstrate Dominance.
Clown species can form pairs, but this should not be taken for granted; instead, it should be viewed as an anomaly.
The Eastern Indian and Western Pacific waters are home to this species. They are also found in Japan, Southeast Asia, and Northern Australia.
At a maximum depth of 15 meters, Amphiprion ocellaris usually inhabits protected lagoons or outer reef slopes in small groups.
It lives in symbiotic partnerships with three different species of sea anemones: Stichodactyla gigantea, Stichodactyla mertensii, and Heteractis magnifica.
The fish Amphiprion ocellaris is nocturnal. Because it is a protandrous hermaphrodite, the male may change its sex at any time.
It also lives in a harem, where group members are kept at a particular social position and are governed by a well-established hierarchy of Dominance.
It is reliant on its sea anemone and exhibits aggressive territorial behavior.
How aggressive are clownfish
Despite their seemingly laid-back appearance, clownfish are quite aggressive fish. However, this does not imply that they actively seek out altercations.
When the conditions are correct, these fish become hostile.
For instance, the clownfish would opt to fight the smaller fish to protect its territory if it intrudes into the area of the fish tank.
As far as fish go, this is stunning, normal stuff. When other fish enter what they perceive to be their domain, many different fish species react in this manner.
Clownfish are likely to locate and occupy a location in the fish tank if not hosting an anemone.
They’ll stay put in that one area of the aquarium.
Why are clownfish aggressive
There are several causes for your clown fish’s extreme aggression, especially when it comes to the other fish in the aquarium. Let’s examine the potential causes of these fishes’ extreme territoriality and aggression.
1. Insufficient Food
Clownfish may face food scarcity in the wild due to competition with other, frequently larger fish species for the same food supply.
They must be bold and self-assured to guarantee they can sit at the table and feed their families.
The fish will become sufficiently irritated if you feed them incorrect or insufficient food, and they will once more turn to rage to release their displeasure.
The feeding period will quickly become chaos, complete with biting, charging, chasing, and shuddering.
2. Nerine
Distinguished by their vivid hues and harmonious coexistence with anemones, clownfish typically exhibit a serene and tranquil disposition.
However, they occasionally let loose their inner Hulk and have temper tantrums.
They’ve had too many espresso glasses.
The clownfish would naturally consider the anemones in the aquarium its home and protect them at all costs.
3. You Selected Incorrect Tank Partners
Clownfish are violent and territorial animals, as we have seen.
Furthermore, they will take action if kept in a setting where they perceive themselves as open to assault.
In most situations, the ensuing bullying and fights can even be lethal.
4. Achieving Dominance
The two clownfish in your aquarium may still need to be teamed up. It takes a while for newly acclimated clownfish to assume charge in a pair.
This implies a good deal of conflict. Everything should get calmer once the dominating female appears.
The mated couple will bully the subservient fish if you have more than one clownfish. Maintaining at most one or two clownfish in a tank is preferable since they will always fight among themselves.
Do clownfish get along with other fish
Many marine fish species coexist with clownfish, such as wrasses, gobies, surgeonfish, butterflyfish, damsels, dottybacks, foxfaces, and more.
Clownfish often get along with other fish as long as they’re not big enough to consume them.
Clownfish may coexist peacefully in tanks with a wide variety of fish species; however, some species are not suitable matches for them. These consist of groupers, lionfish, and several species of clownfish.
1. Tiny Angelfish
Clownfish get along nicely with Angelfish of all kinds. Nonetheless, because Pygmy Angelfish are more closely matched in size, I suggest them.
Avoiding significant kinds of Angelfish is advised because many of them can be a little aggressive.
Most of Pygmy Angelfish’s diet consists of grazing species such as bryozoans, algae, sponges, and other encrusting creatures on living rock. Unfortunately, this means that most species are not safe for the reefs.
But their bright colors and gregarious personalities more than makeup for it.
Some excellent invertebrate clownfish tank mates include toadstool, hammer, and mushroom corals. The clownfish may make a home there and regard it as a surrogate anemone.
Those corals are all commonly accessible as aquacultured species and are often harder than anemones. That is entertaining to watch.
2. Fish with Mandarin
If you have a one-year-old Clownfish in a 30-gallon tank with rocks shaped like a small reef, consider keeping a Mandarin Fish (Synchiropus splendidus) as a tank mate.
Clownfish and mandarin fish make excellent aquarium companions. Both are tranquil and modest in size.
In addition to not being territorial, because they inhabit a distinct area of the tank and are bottom dwellers, Mandarin Fish will not trespass into the Sea Anemone they share.
Mandarin Fish’s diet necessitates that the rock be at least a year old.
Their primary food source is copepods, tiny zooplankton that frequently merge with mature reef rocks.
Final thought
Now that we have established that clownfish are aggressive, we should be aware that there is a rigid order of authority among clownfish in a group.
At the top is the most extensive and most aggressive female. There are just two clownfish in the group—a male and a female. Because clownfish are sequential hermaphrodites, they grow into females after initially developing into males.
A female Clownfish will spawn from one of the group’s biggest and most dominant males if the female is removed.
The surviving men will advance in the hierarchy. Any level surface near their host anemones is where clownfish deposit their eggs.
Clownfish reproduce in the wild during the complete moon phase. Hundreds of thousands of ova may be laid by clownfish, depending on the species.
Typically, the male parent supervises the ova from two hours after nightfall until they hatch six to ten days later.
In summary, it is imperative to use extreme caution and diligence when establishing a clownfish tank. Without a doubt, they are territorial and aggressive.
Nevertheless, if done correctly, there shouldn’t be any problems, and let’s face it—these tiny fish are really cute!
