Determining Chum's age is not an exact science by any means. However, certain characteristics can lead one to believe whether or not it is young, adult, or senior. If longer than about 3cm, it is most likely at least an adult. If you look at the fins, if they appear to be completely in tact, robust, and unfaded in color, you likely have an adult rather than a senior fish. More elderly fish tend to swim less and will tend to spend more time hiding behind objects if available. Older fish, betta included, can also have characeristic cloudiness to the eyes, known as cataracts.
