in the aquarium. Aggressive fish are often carnivorous and
eat other small fish in the tank. You may be keeping this aggressive fish for
fun or not knowing in the first place that they are aggressive. So here are the top 10 aggressive aquarium
fish that you need to know. Number 10, Arowana
Arowana are freshwater bone tongue fish as you might already know. They can swallow fish or other creatures that
are smaller than their mouth size or that fits in their mouth. Arowana are carnivorous and surface feeders. They originate from South America and often
called water monkeys because they jump up to 6ft above water to catch insects and other
creatures. Arowana species typically grow to around 2
to 3 ft. in captivity and are aggressive fish that eats smaller goldfish, insects or even
small rats. Number 9, Redtail Catfish
Redtail Catfish are another extremely popular fish in Amazonian themed exhibit where they
are housed with another such large fish like Pacu or similar larger catfish. They can grow to large size very quickly and
are best kept in aquariums of 2600 US gallon or large outdoor ponds when they grow to adult
size. Redtail Catfish can easily swallow common
tetras when juvenile and when they grow up they can swallow fish that fit in their mouth. Number 8, Oscar Fish
Oscar fish are another aggressive fish in the list. They lay to claim an area of the aquarium
and will be very aggressive towards other fish encroaching on their newly established
territory inside the aquarium or lake. The species uses a suction mechanism to capture
prey and reported to exhibit laying on side mimicry to approach its prey. Captive Oscars generally eat fish food designed
for large carnivorous fish like crayfish, worms, and insects (such as flies, crickets
and grasshoppers). Number 7 Paroon Shark
Paroon Shark or giant pangasius are also aggressive fish that are critically endangered. Full-grown adults can reach 300 centimetres
(9.8 ft) SL in length and weigh up to 300 kg. Juveniles and adults feed on crustaceans and
fishes. So they need large aquariums or pond and are
kept with large tank mates because any smaller fish that fit their mouth will be swallowed
by the Paroon Shark. Number 6, Alligator Gar
Alligator Gar are the largest species in the gar family and among largest freshwater species
in North America. Reports suggest they can grow up to 10 ft
that is 3 m in length, and weigh as much as 159 kg. Alligator gar are relatively passive, seemingly
sluggish solitary fish, but are voracious ambush predators. They lunge forward, and with a sweeping motion,
grab their prey, impaling it on their double rows of sharp teeth. Number 5, Wolfish
As you can see wolfish are another aggressive or predatory fish that can eat other small
fishes in the aquarium. Their mouth are full of rows of sharp teeth
which they uses to capture the prey and eventually swallow them as a whole. Here you can see how it is positioning the
prey fish and swallowing it and Fish could just say lol from the mouth. Number 4, Snakehead
They are valuable as a food source and have become notorious as an intentionally released
invasive species. That is they cause destruction in large number
and the absence of natural enemies gives them apex predator status. Each spawning age female can release up to
15,000 eggs. Since 2002, it has been illegal to possess
a live snakehead in many US states, where they are considered a destructive invasive
species. They are aggressive fish and attack and eat
smaller or larger fish in the aquarium. Number 3, Vampire Fish
Vampire Fish or Payara is an aggressive aquarium fish. This predatory fish is found in the Amazon
Basin in tropical South America. The payara, which is also sold as the saber
tooth barracuda, vampire fish, vampire tetra, or saber tusk barracuda, is a popular species
for large, aggressive aquariums. It requires a large aquarium and can only
be mixed with relatively large species, as smaller will be seen as potential prey. Number 2, Goliath Tigerfish
It is African freshwater predatory fish found in Congo River basin. It is carnivorous fish, feeding on any fish
it can overpower. It is very aggressive even when it is juvenile. Goliath Tigerfish can grow to 1.5 metres and
weighing as much as 50 kilograms. A number of incidents have been reported in
The Congo of this fish attacking humans. According to locals living near the river,
the evil spirit “mbenga” would enter the fish and make it attack people. Now that is very strange. Number 1, Red-bellied Piranha
Number 1 in the list is Red-bellied Piranha. Through media influence, the red-bellied piranha
has developed a reputation as a ferocious predator, though this is not actually the
case. They are a popular aquarium fish. However their jaw bone is packed with razor
