Some tropical fish are difficult to keep.
There are some types of tropical fish that are difficult to keep, but there is a difference in the degree of difficulty in breeding between the original species and the improved species.
In general, we tend to think that there are rare fish species and expensive fish species that are difficult to breed, but in fact, there are species that are surprisingly difficult to breed, even among popular species that are often seen anywhere.
This time, I will introduce tropical fish that are difficult to keep, so I hope that even beginners can refer to them.
Top 10 tropical fish that are difficult to keep!
Although breeding is generally difficult, there are various reasons. I tried to summarize it in the ranking by dogmatism and prejudice.
No. 10 Guppy
Guppy, which is both a popular species and a small fish, is the easiest fish to breed, including goldfish and medaka, and is often recommended for beginners.
On the other hand, because it is a small fish, there is also a weak side. Foreign guppies are vulnerable to environmental changes when imported, and domestic guppies are susceptible to diseases from foreign guppies. But for guppies, if you feel something is wrong, just give them a 0.5% salt water bath and they'll be fine./
No. 9 Discus
Discus is often referred to as the king of tropical fish, so it has characteristics that other fish species do not have when it comes to breeding. For example, the water temperature should be at least 28 to 30 degrees Celsius, and 31 to 32 degrees Celsius for juvenile fish. The aquarium will also be a bare tank breeding.
If you do not know that there are breeding conditions that other fish species do not have, you will find it difficult to breed them. In addition, not only discus, but also cichlids, it is important to maintain a balance of power, so knowledge and experience will be useful for mixed swimming.
No. 8 Platy
Platy is a popular breed, but there are cases where it is out of order when it arrives, so in such cases, it may die without knowing the reason. Regarding the bad condition at the time of arrival, if the disease is cured and immunity is built up, it is not weak in constitution, so it can be said that it is an easy fish to keep.
Another aspect that is difficult to keep is that there may be individuals that poke other fish persistently, so on the contrary, large fish such as gouramis and angelfish are easy to target because they have a large target, and they may be poked and killed by platy, so be careful.
No. 7 African lamp eye
Small fish are small, so it can be said that small fish in general are generally weak, but considering the situation when they arrive from wholesalers, African lampeye is one of the fish that often arrives in poor condition. For that reason, it can be said that it is one of the fish species that are difficult to keep if the conditions are not stable.
If it arrives in a bad condition, it is a fish species that can be wiped out even at the store, so the treatment at the store is also important. Not only African lampeyes, but small fish basically have such characteristics, so be especially careful when purchasing./
No. 6 Neon Dwarf Grammy
This breed is an improved version of the Dwarf Gouramis and is a popular breed, but it is surprisingly difficult to keep. It's fine if nothing happens, but improved Dwarf gourami (cobalt dwarf gourami, sunset dwarf gourami, etc.) can suddenly die due to swollen internal organs and bumps on the body.
Although it can be bred and bred in an environment where it is just filled with water in a plastic case about 30 cm, it may show such weakness.
No. 5 Clown Loach
Roaches such as clown roach and coolie roach are more susceptible to white spot disease than other fish species, so be careful.
However, white spot disease in freshwater fish is28You don't need to be so nervous because you can easily treat it by raising the temperature above the degree.
From this point of view, it is better to mix the crown roach with fish species that can be raised at high temperatures.
4th Green Pufferfish
Green pufferfish is also a popular species that has been well known for a long time, but it is one of the fish species that is difficult to breed. Green puffer fish are basically kept in breeding water with a certain degree of salt concentration, such as brackish water, so it is a difficult species to keep in freshwater for a long time.
In addition, green puffer fish can be kept in small tanks as long as the water is changed frequently or the filter bacteria are functioning well.
3rd place Morley
The popular molly (black molly, selfine molly, balloon molly, etc.) is surprisingly difficult to keep for a long period of time. Molly is vulnerable to acidity, so it can be said that it is vulnerable to old water (water quality deterioration).
Molly is actually a fish species that can be bred better in brackish water or water with a little salt. Therefore, if you gradually get used to the water quality, you can raise them in seawater, so you can swim with saltwater fish, and you can see a mysterious aquascape./
No. 2 Orange Fin Kaiser Pleco
Other plecos can also be said to be corydoras and other catfish, which are also related to catfish, but catfish are vulnerable to fish disease drugs, so they are more difficult to breed than other fish species when disease occurs.
When using fish disease medicine, dilute it to 1/2 to 1/3 of the prescribed amount. Speaking of plecos, self-fin plecos, which are also moss-removing plecos, are very strong, but orange fin Kaiser plecos can die suddenly even if they are kept in good condition, so they are particularly difficult.
No. 1 Arowana (baby)
Let alone black arowana babies, even silver arowana babies are prone to die unless they are raised and managed with care.
About 10 cm in length should be kept with care, and individuals smaller than 10 cm should be managed with great care. Specifically, do not let them swim together. If you swim with other fish, you won't be able to eat bait well, and in some cases, you will be killed by mixed swimming fish. There is no problem with swimming with small fish that become bait./
tropical fish for beginners
The first recommended tropical fish for beginners is red fin. Strictly speaking, the red fin is not a tropical fish, but considering that it is a small fish, it can be said that it is a very hardy fish.
The other is Neon Tetra, but there are some weaknesses due to small fish. However, it can be said that it is a tropical fish for beginners because it has the power to withstand dirt in the water. Neon tetras are also inexpensive like red fins, so they have the advantage of being easy for beginners to purchase.
In addition, there are many types of large fish that are hardy and easy to keep, but you need to be careful that you need a large aquarium. Despite its relatively small size, the Blue Tiger Parrot (Snow White Parrot) is recommended for beginners because it is as robust as large fish./
Tips for successfully raising tropical fish that are difficult to keep
Knowledge and experience are required to successfully breed difficult tropical fish, but beginners tend to focus only on the fish species. Books such as tropical fish encyclopedias describe the water quality and temperature for each type, but in fact, it is not necessary to be so particular about the pH, such as weak acidity or weak alkalinity.
What is more important than that is more basic things, such as doing safe water changes with safe water, knowing the mechanism of filtration, being able to read the current state of the tank, knowing the habits of the fish, and managing it as regularly as possible.
Let's firmly hold down the point that it is important to know what is necessary for each fish species with those basics.
Still, you should try to keep a tropical fish that you care about!
This time, I picked up some tropical fish that are difficult to keep and introduced them.
Before that, it's a good idea to practice raising and breeding with fish species that are similar to the target fish species. By the way, I practiced with angelfish before I got discus. You can be good at what you like. While using this article as a reference, at the end, try raising your favorite tropical fish.
