First, cold water fish
If you like cold water fish, keep them in koi fish. Although it is "Japanese", it is better to keep and the requirements are not high.
If you are patriotic, keep some goldfish. There are many kinds of goldfish, but generally there is no scientific name. There are "big eyes" and "crane top red" in spoken English.
If you want to raise some special cold-water fish, you can raise hexagonal dinosaurs, thrush and sunfish. Hexagonal dinosaurs are easier to raise here, while the other two are more expensive and hard to buy.
Second, tropical fish
Tropical fish can be divided into two types, small ornamental and large carnivorous.
1, the small ornamental category is more suitable for beginners, the most common is phoenix tail, as well as traffic lights, Moli fish, tiger skin, colorful skirts and so on. , and more. However, I personally think that raising small fish in such a big tank must win by quantity and win by scenery. If it is a bare tank, it is not recommended to raise small fish. The disadvantage of raising small fish is that it is troublesome to mix and match. It is necessary to know the habits of each kind of fish. For example, tiger skin and phoenix tail are not suitable for raising together, and angelfish like to be quiet and cannot be raised with naughty blue sharks.
2. Big fish are generally fierce and expensive. The more expensive ones are tiger shark, seven-star knife, golden dragon and silver dragon. These big fish are also very troublesome to mix together because of individual differences. Generally speaking, Jinlong and Yinlong are versatile, and they mainly move in the upper water. It's better to be careful when mixing other fish.
To sum up, I suggest that if you are a beginner, you'd better not mix them. I suggest you keep some blood parrots, which are beautiful and feng shui fish. It's easier to keep them (but it takes some effort to color them). There are also some tool fish that must be kept. If you raise big fish, you will mix scavengers; if you mix small fish, you will mix mice, such as golden-haired mice and bronze mice. It should be noted that most of these tool fish are tropical fish. Keep them, and it will be less troublesome to clean them up, hehe.
