Tips for picking fish: how to choose healthy and good fish?

I believe many friends have a heart for raising fish. After all, those colorful little guys swimming around in the water are beautiful, but they are nervous because they can't pick fish. Picking fish is really a technical job. Today, Bian Xiao, I will introduce you to some traditional methods of selecting healthy and good fish.

First: don't pick the fish that swings from side to side.

If you pick fish in a physical store and see some fish hanging around in the fish tank for a few minutes, then this fish is probably sick and very sick. Generally speaking, healthy and normal fish will swim around in the water, so those fish that stay in the water and sway from side to side are all fish that have no strength to swim, and they are already very weak. They have to constantly sway from side to side to ensure that they will not sink to the bottom of the tank.

Second: Don't pick the fish hiding in the corner.

Usually, the fish in the fish tank will hide in the corner of the fish tank only when they have just arrived in a new environment. In this case, it is often a group of fish hiding in the corner together, so if individual ornamental fish are found hiding in the corner and do not participate in their group activities, then this fish is not necessarily sick, but it is also a fish with less courage or weak body, and it is not easy to raise after buying it.

Third: don't pick fish that rub things.

You may think, what does this fish rubbing things have to do with the health of the fish? Bian Xiao is here to tell you that this has a lot to do with it. It doesn't matter if you just wipe it once in a while. If rubbed regularly, most fish have parasites in their bodies. Fish have no hands, so they don't feel as bad as we do. All they can do is scratch around with their hands. All they can do is keep rubbing the fish tank or all kinds of equipment. So you can't have such beautiful fish.

Having said that, it is not recommended to buy, so let's talk about recommending to buy.

First: Choose fish that like to chase other individuals.

Everyone who raises fish knows that there will always be one or several "tank tyrants" in a fish tank, which means that there will always be some strong fish in the fish tank that will catch up with other fish. This kind of fish is called "tank tyrant". Don't hesitate to buy such fish, because most of them are in excellent health.

Second: choose to grab more aggressive fish.

Just like children eating, the strong one can grab more food, and so can the fish. Moreover, if a fish doesn't grab food well, it means that it has a good viability and a good nutritional supplement before, so don't worry too much about whether they will adapt to the new environment.

The above is a simple summary I gave you. In a nutshell, it is to achieve "three don 'ts" and "two musts". I believe that as long as we can do this, we will never worry about not picking healthy and good fish.
