The term painted fish
refers to ornamental aquarium fish
which have been artificially coloured to appeal to consumers. This artificial colouring, also known as juicing
, is achieved by a number of methods, such as injecting
the fish with a hypodermic syringe
containing bright fluorescent colour dye
, dipping the fish into a dye solution, or feeding the fish dyed food.
This process is usually done to make the fish a brighter colour and more attractive to consumers. The colouring of the fish is not permanent, and usually fades away in six to nine months.
