Zebrafish can grow up. The adult zebrafish is about 3-4cm in length, and some larger zebrafish can grow up to 7cm in length. The growth rate of zebrafish is very fast. Zebrafish with a length of about 2cm can grow up in about 2 months.

and zebrafish are well-bred, they do not require high water quality during the growth period. It also grows very fast. If the water temperature can be controlled well during the breeding period, the growth rate of zebrafish will be faster.
