When purchasing new ornamental fish, you should abide by the following principles:

1. Choose larger ornamental fish. In the same nest of fish, larger ornamental fish generally have strong disease resistance, strong appetite and rapid growth, which will reduce a lot of trouble in the future raising process. A smaller body means it has weaker vitality and poorer health.

2. I would rather have a brand than a low price. It is generally safer to buy fish from aquarium stores with better brands and reputations. Larger aquarium stores generally have strict requirements and inspections on fish. Low-quality and cheap commercial fish may contain surface parasites or internal pathogens, which may make you prone to illness after you purchase them and return home.

Ornamental fish live in water, and their body surfaces are easily contaminated with bacteria. Generally, various microorganisms are attached to the body surface of fish. When the fish's immune function is normal, it can resist the invasion of pathogenic microorganisms. However, when the fish is purchased and brought home, the fish's immunity rapidly declines due to excessive fright and stress, and pathogenic microorganisms can easily invade the fish. , leading to disease.

This is an important reason why ornamental fish were very active when purchased at the aquarium store, but began to become ill after returning home. Therefore, before new fish are put into the tank, they must be put into the fish bag with 3% salt and soaked for 15 minutes to kill some pathogenic microorganisms on the body surface before the fish can be put into the fish tank. If the fish tank has been cultured with beneficial bacteria, it can serve as a double insurance and minimize the chance of fish disease.
