2. Look at the specifications.
Small size is appropriate, but if it is too small, the fish body will be too fragile and difficult to accept the transportation process and new water environment, especially for fish with high requirements for water quality and dissolved oxygen. It is difficult to survive, so it is better to buy young fish.
The size of juvenile fish varies depending on the size of the individual adult fish, and can be divided into three categories:
For small fish with a body length of only a few centimeters, choose juvenile fish of more than 2cm or about 3cm; For medium-sized fish around 10cm, choose juvenile fish of 4-5cm, and for large fish, choose juvenile fish of 6-9cm.
In the same nest of fish, some large juvenile fish are selected. Some large juvenile fish often grow faster and larger, while some small ones are often larger and much better, and some even fail to reach the specifications.
