Fish culture consultation fish tank fish culture consultation?

Choosing a healthy and good fish is also a technical job. When you walk into a fish shop, you are often dazzled by the beautiful fish in the jar and feel that everything is fine. However, it is not easy to choose the best fish from them. The basic principle is to choose those fish with stretched fins, elegant tails and fast swimming. Don't trust the seller's recommendation easily. You should have the mentality that you would rather miss than buy wrong, and believe in your choice. The key is to buy fish and go home. Don't put the fish tank in a hurry, but put it in a spare tank or other container for two days to see if there is anything wrong with the fish, and then put it in the main tank after confirmation.
