As for some imported high-grade angelfish, the beauty of color and the elegance of swimming are far beyond the comparison of ordinary fish, and they are really popular. While maintaining this luxury hobby, how to close your pockets and buy healthy and satisfying fish?

1. It is very helpful to choose a trustworthy aquarium store and visit several aquarium stores before buying fish. First, you can understand the business reputation of the store, and second, you can grasp the quality and price of the fish, and Increase farming knowledge. Buy from a store with a good quality and reputation. Don't buy fish that are too cheap to buy. It may be the outdated fish that the store does not want to store, or it has a dark disease, or it is extremely difficult to raise. Buying these poor quality fish will not only fail to feed but also harm other fish in your aquarium. Some fish are caught by poisoning and explosion methods. At first glance, they are no different from normal fish, but their internal organs have been damaged, and they will die soon after being raised. The mortality rate of fish in some fish shops is very high. The fish are hung in the tank with potion, and the layman can't see it at all. Those who are unfamiliar with the market should be careful to be hiked in price, so buy at a familiar aquarium store. Every aquarium store uses different seawater, and buying from the same store reduces the risk of fish acclimatization.

2. Buy healthy and lively fish. Before buying fish, you must carefully observe their health status. Healthy marine fish have clean and shiny surfaces, swim freely in the tank, and can quickly escape when they encounter changes or shocks. Those who are short of breath, slow to respond, always stop near the circulation port and open and close their mouths rapidly or hide in corners without moving, are unhealthy fish. Do not buy thin fish, do not buy fish with cloudy eyes or protruding eyes, do not buy fish whose body is often wiped by the tank, do not buy fish with peeling scales or spots, and do not buy fish that are injured or have unknown attachments.

3. Juveniles that have just hatched have weak vitality. Once they reach the juvenile stage, they are full of vitality and are easy to adapt to various environments. This is the best choice. The adult fish is not suitable for buying because it is not easy to tame the bait and its vitality gradually declines.

4. When buying fish that have already been eaten, be sure to ask the store to feed them on the spot when buying fish, and strong fish must grab it. If the fish are willing to accept artificial feed, it means that the store has already tamed the bait, which can save a lot of trouble. You must know that the fish is easy to succeed in baiting in a naked tank. And the attack of old fish, it may continue not to eat, which can be dangerous.

5. Buy suitable fish according to the situation of your aquarium. Buy the right fish according to your home environment, the size of the aquarium, the availability of software and other factors.
