Hello aquarists! If you have any ornamental fish breeding problems, you can directly search for fish farming and keywords throughout the network, so that we can easily raise water and raise fish happily.
It is not suitable for polyculture, does not mean that it can not be polycultured at all, such as: Luohan, electric eel, thunder dragon, s genus water tiger, etc., these can only be raised alone ornamental fish except.
First, the large size of the walrus fish
The scientific name is Arapaima, and its strength is the crown of ornamental fish.
The huge size of this big guy will cause a huge sense of oppression to other ornamental fish, and if there is a free fighting competition for ornamental fish, he is definitely the existence of heavyweight boxing.
Ordinary other fierce fish, it is difficult to make them lose blood, the whole body is covered with layers of armor, and the ordinary attack power is more harmful than the big moves launched by other fierce fish.
If it weren't for the Magic Damage South American electric eel, this guy would definitely have few rivals in the same waters or even the entire freshwater fish, and the weak ornamental fish raised in the same tank would be difficult to survive.
Moreover, this guy can eat thieves, and those who can afford it are undoubtedly local tycoons, and they are persistent local tycoons.
Second, the king of catfish, Satan duck-billed catfish
A large fierce fish of the same magnitude as the walrus fish, satan's title is enough to illustrate its terrible point, as an enhanced version of the fortune cat, for most ornamental fish, it is a nightmare existence.
The ornamental fish in the same tank as it, in front of him can be said to be the lamb to be slaughtered, and the prototype of many regional "water monsters" is this guy.
3. Jade crown, red-tailed crown
Compared with other large ornamental raptors, they are not very powerful, but their personality is like a flat-headed brother.
That is life and death, do not obey!
The pectoral fin, dorsal fin and tail fin of the fish in the same tank are often bitten and cracked, and the mouth is very indebted, and many aquarists who have raised the crown are very headaches about it.
4. Ten fish in Africa
Along with the Jade Crown, it is called a war dealer among medium-sized ornamental fish.
Can stir the fish tank is turned upside down, this guy's characteristic is where to fight, no matter how many times you pour it into the tank, just like taking poison, you can't change it, you can't change it, you can't make a mistake, it's definitely a rogue element in the fish.
5. Ghost RocketFish
Belonging to the albino alligator eel, it is also a heavyweight player, as an invasive alien species, its personality is the same as its colleague Brazilian turtle, that mouth of sharp teeth, the prey he bites is like being bound by a stapler, how to struggle can not get rid of.
There are also its scales, like the giant bone snake fish is also fully armed, thick ordinary armor, just such a double first-class guy with attack power and defense, in his native North America, that is, the lord of the king, and almost no fierce fish in the water can match it.
Many aquarists who have raised alligator eels have experienced that the ornamental fish in the same tank, the fish body is bitten by hole, and the scales are full of tanks, which is very annoying.
5. Red-tailed catfish
Commonly known as the Emperor of Unity, its stomach that can never be filled has caused many aquarists a headache.
When we were ready to feed the fish, we found that some ornamental fish had disappeared, observed for a long time, and saw the bulging belly of the Zhao Cai cat, and in an instant, the ability to swallow everything was really a bit inexplicable.
This guy never looks at the menu when he eats, and no matter how expensive the ornamental fish are, it's all its fish food.
6. Nile manta rays
Also called the Anti-Heaven Knife, the Fish Tank Mixed World Demon King of the Eight Classics, its teeth are like its body shape, often bite the prey in half, it can really be explained by blood once, every time you eat live food, aqua friends can see the full tank of blood mist.
There is no softness towards the fish in the same tank as him, and the scalpel-like teeth are definitely a nightmare for most ornamental fish, not only that, this guy can also release a weak current, but also a master who knows weak spells.
7. Large jaw and small fat carp
Also known as the Golden River Tiger, a fierce character, a bandit with a special personality, the key family is also very powerful, that sharp tooth is the culprit of the chaos fish tank, often attacking other fish, even if it encounters a much larger than their own arapaima, they dare to go up and do it.
The giant dog fat carp in the same tank, Colombian giant storm has been suppressed to death by it, and is a real ornamental fish saint seiya! Worthy of the title of Tiger in the River.
VIII. Large pencil fish of the family Ichthyidae
This fish is large and aggressive, and has a fight with the blackfish of the mainland, and is also an important fighting force of the snakehead fish family.
The point is that people have a very good skill, death shake head, which is the famous skill of crocodiles and sharks, and the gifted one will often be the initiator of murder in the fish tank.
IX. Genghis Khan Shark
The giant catfish in the Mekong River, because of its predatory and streamlined body shape, is called a freshwater shark, and it is also a hegemonic presence in its hometown, and it is a virtue with the fortune cat, as long as it is smaller than it, it is included in the recipe.
10. All kinds of dragon fish
Gold, silver, red, black, star dragon, all have, temperament is also very ferocious, territorial awareness is very strong, and valuable varieties are very valuable, it is not recommended to raise other fish, it is best to raise single tank, single fish.
11. Giant dog fat carp, Colombian giant storm
These two do not know whether to rank them in the ranks of non-polyculture ornamental fish or single ornamental fish.
Many aquarists will mix them with the golden river tiger, crocodile eel and other fierce and vicious people, unless it is a heavyweight fierce fish with full offensive power and defense power such as arapaima and crocodile eel, and other fierce fish are in front of them, even if they can't get good fruit to eat.
12. Stingray
It is a living fossil of the same period as the dinosaur fish and the arapaima.
This guy looks cute on the outside, but in fact he is as terrifying as the lionfish in the sea, although he also eats four squares with a big mouth, and unlike the fortune cat, they can bury other small fish under them with only their huge size, have no place to escape, and then swallow them in one bite.
The above-mentioned medium and large fierce ornamental fish that are not easy to polyculture, in addition to being very aggressive and may pose a threat to other ornamental fish, many species also have a commonality, that is, eating more and pulling more, and the large amount of feces discharged is very easy to pollute the water quality!
Raising them requires super large and powerful filtration in fish tanks, and even if different species of the same size are mixed together, there may be casualties.
I am a veteran of fish farming, more ornamental fish problems please pay attention, thank you!
