1. Goldfish Goldfish are a common wide-temperature bush fish with a long history of cultivation in my country. They are usually divided into four types, namely grass type, literary type, dragon type and egg type. Among them, grass type goldfish is the most widely bred variety, which is not only beautiful in appearance but also easy to raise. Egg type is a more popular variety in recent years, with a round and cute appearance.

2. Arowana Arowana is a large ornamental fish and an ancient primitive fish species. It is native to Southeast Asia and is already very rare in the wild, but there are many in captivity. As a tropical fish, it has certain requirements for water temperature, which should be kept above 24°C. In addition, during the breeding season, the male fish will hold the eggs in its mouth to protect them.

3. Guppy Guppy is a very common small tropical fish. There are many types of it, and the colors are also rich. No matter which one it is, it has a beautiful big tail. It is worth mentioning that guppy is a very easy-to-raise ornamental fish, with strong adaptability to the environment and easy to breed, which is especially suitable for beginners to practice.

4. Parrot fish Parrot fish is an artificially cultivated ornamental fish, which is also quite popular at present, mainly because of its bright red color, so it is very popular in China. Due to the congenital defects of this fish, it has a high demand for oxygen, and needs a high dissolved oxygen content to keep it alive. In addition, attention should be paid to feeding and water temperature to keep its body color bright.

5. Koi Koi, like goldfish, is a wide-temperature fish, but it is relatively large and requires a larger fish tank to keep it. However, it does not require high water quality and has a more diverse diet, so it is still very easy to keep.
